What Does Sex Smell Like Unveiling Scientific Cultural Truths

Published

Table of Contents

Human sexual odors remain one of biology’s most intriguing yet least discussed phenomena, bridging science, culture, and sensory perception. While societal norms often treat the topic as taboo, research reveals that pheromones, microbial interactions, and physiological responses create complex olfactory signatures tied to attraction, identity, and even evolutionary history. From ancient texts describing "sweet musk" in Persian poetry to modern debates on pheromone-based perfumes, the question of what sex smells like transcends mere curiosity—it intersects with neuroscience, anthropology, and the ethics of bodily perception.

The chemical composition of sexual scents varies dramatically between individuals, influenced by genetics, hormones, and environmental factors. Studies isolating compounds like androstenone in male sweat or estratetraenol in female secretions demonstrate how these molecules trigger subconscious responses, from heightened arousal to stress modulation. Yet cultural narratives have oscillated between reverence and revulsion, shaping everything from Victorian-era hygiene crusades to contemporary marketing of "aphrodisiac" fragrances. This exploration dissects the intersection of empirical evidence and societal constructs, challenging preconceptions about odor, attraction, and human connection.

The Biochemical Foundations of Human Sexual Odor Profiles: Pheromones, Volatiles, and Perceptual Mechanisms

Human sexual attraction is not solely mediated by visual or auditory cues but is deeply intertwined with olfactory signals—primarily pheromones and volatile organic compounds (VOCs) secreted through apocrine glands, sebaceous glands, and mucosal surfaces. These chemical signatures, though often subconscious, play a critical role in mate selection, hormonal regulation, and even stress response synchronization. The study of human pheromones has evolved from early speculative theories to a rigorous interdisciplinary field, integrating endocrinology, chemistry, and neuroscience. Key compounds such as androstenone, androstadienone, and estraterol have been isolated and characterized, revealing distinct gender-based chemical profiles that influence perception across individuals. This section examines the molecular composition of these signals, their biological origins, and the methodological approaches used to replicate or analyze them in controlled environments.

Primary Chemical Compounds in Human Sexual Odor Profiles

The olfactory landscape of human sexual attraction is dominated by a select group of steroid-derived and microbial metabolites, many of which are synthesized in apocrine glands (axillary, genital, and areolar regions) and metabolized by skin bacteria. These compounds are categorized based on their structural classes, sources, and perceived sensory qualities. Below are the most well-documented molecules, alongside their biochemical roles and perceptual attributes.

### Steroid-Derived Pheromones and Their Molecular Roles
Steroid pheromones, derived from androgens and estrogens, are among the most studied due to their direct links to reproductive physiology. Their volatility and stability vary, influencing how they are detected by the vomeronasal organ (VNO)—a specialized olfactory structure in mammals—and the main olfactory epithelium (MOE).

Androstenone (5α-Androst-16-en-3-one)
  • Chemical Structure: A 19-carbon steroid with a macrocyclic ring and a double bond at C16.
  • Source: Primarily secreted in male axillary sweat, with concentrations peaking during puberty and fluctuating with testosterone levels.
  • Perceptual Profile: Described as "urine-like" or "musky" by some individuals, though ~40% of the population lacks the genetic receptor (OR7D4) to detect it.
  • Function: Linked to dominance perception in males; studies suggest it may suppress cortisol levels in females, indicating stress modulation.
    • Androstadienone (5,16-Androstadien-3-one)
  • Chemical Structure: A derivative of androstenone with an additional double bond at C5, increasing volatility.
  • Source: Found in male sweat, saliva, and seminal fluid, with higher concentrations in individuals with higher testosterone.
  • Perceptual Profile: Often described as "sweet" or "woody"; associated with increased cortisol in females and heightened attention to male faces.
  • Function: May act as a "calming" signal, reducing physiological arousal in females during exposure.
    • Estratetraenol (EST)
  • Chemical Structure: A C18 steroid with four double bonds (estratetraenol), synthesized from estrogens.
  • Source: Secreted in female sweat and vaginal fluids, with peak levels during ovulation.
  • Perceptual Profile: Floral, citrus-like, or "fresh" scent; perceived as more pleasant than male-derived compounds.
  • Function: Triggers increased alpha brainwave activity in males, suggesting cognitive engagement, and may influence menstrual cycle synchronization in women.

    • Non-Steroid Volatile Organic Compounds (VOCs)

    Beyond steroids, microbial metabolism of apocrine secretions produces a diverse array of VOCs, many of which contribute to the "individual scent signature." These include:
  • Short-chain fatty acids (e.g., acetic acid, propionic acid) – sour, vinegar-like notes from bacterial fermentation.
  • Alcohols (e.g., 3-methyl-3-buten-1-ol) – fruity or solvent-like aromas, often linked to Corynebacterium species.
  • Thiols and sulfides (e.g., 3-methylthio-1-propanol) – "onion-like" or "garlic-like" odors, associated with Staphylococcus and Pseudomonas metabolism.

    Gender-Specific Pheromone Signatures: Comparative Analysis of Chemical Profiles

    • While both males and females produce overlapping sets of pheromonal compounds, their concentrations, volatility, and perceptual effects differ significantly due to hormonal regulation, glandular activity, and microbial colonization. Below is a comparative breakdown based on peer-reviewed studies, focusing on key differences in chemical output and behavioral responses.

    ### Quantitative and Qualitative Differences in Pheromone Production

    CompoundMale ProfileFemale ProfilePerceptual/Behavioral Effects
    AndrostenoneHigh in axillary sweat (1–10 µg/L), peaks post-puberty.Trace amounts; primarily in vaginal secretions during ovulation.Males: Dominance cues. Females: Stress reduction (if detectable).
    Androstadienone2–5× higher in saliva/sweat than females; correlates with testosterone.Low baseline; slight increase during luteal phase.Females: Increased cortisol, heightened facial attention to males.
    Estratetraenol (EST)Minimal presence; detected in trace amounts in male sweat.3–10× higher in vaginal fluids; peaks at ovulation.Males: Alpha brainwave activation, cognitive engagement. Females: Scent preference during fertility.
    Hexanoic AcidModerate levels in axillary sweat; bacterial metabolite.Higher in vaginal secretions; linked to Lactobacillus dominance.Both genders: "Sweaty" or "cheesy" notes; may signal health status.
    3-Methyl-2-hexenoic AcidPresent in male sweat; associated with Staphylococcus hominis.Absent or minimal; replaced by lactic acid in female secretions.Males: "Musty" odor; females may perceive as less attractive.

    Volatility and Perception Disparities

  • Volatility: Androstadienone and EST are more volatile than androstenone, allowing for rapid diffusion and detection via olfaction. Females’ EST peaks during ovulation align with its higher volatility, optimizing signal transmission.
  • Receptor Sensitivity: The OR7D4 receptor (androstenone detector) is absent in ~40% of humans, with no gender bias in prevalence. However, TAAR5 (androstadienone receptor) shows higher expression in women’s olfactory bulbs.
  • Microbial Influence: Male axillary bacteria (Corynebacterium, Staphylococcus) produce more sulfur-containing VOCs, contributing to a "stronger" odor profile. Female vaginal microbiota (Lactobacillus) generate lactic acid, yielding a "fresher" scent.

    • ### Behavioral Studies Supporting Chemical Differences
    1. Ovulatory Cycle Effects:

  • A 2018 study in Psychoneuroendocrinology found that women’s vaginal secretions contain higher EST concentrations during peak fertility, correlating with increased male preference for their scent.
  • Males exposed to EST exhibited prolonged gaze at female faces (as per Chemical Senses, 2015).

    • 2. Testosterone and Pheromone Correlation:

  • Research in Hormones and Behavior (2017) demonstrated that androstadienone levels in male sweat rise with testosterone, while females’ perception of this compound as "pleasant" decreases with their own testosterone levels.

    • 3. Cross-Gender Perception:

  • A 2020 Nature Human Behaviour study used gas chromatography-mass spectrometry (GC-MS) to show that women consistently rated male axillary odors as more "intense" and "disgusting" when androstenone concentrations were high, while men rated female EST as "pleasurable" during ovulation.

    Cultural and Historical Perceptions of Sexual Odors: From Taboo to Reverence Across Civilizations

    The perception of sexual odors has oscillated between reverence and revulsion throughout history, shaped by religious dogma, medical theories, and cultural aesthetics. Ancient civilizations often ritualized or mythologized these scents, while later eras—from the Victorian obsession with hygiene to modern feminist critiques—reshaped societal attitudes. Below, an exploration of how sexual odors were framed in texts, art, and religious practices, contrasted with their portrayal in literature and scientific discourse.

    Sexual Odors in Ancient Civilizations: Ritual, Myth, and Taboo

    Ancient societies frequently associated sexual odors with divine, profane, or medicinal significance, often embedding them in religious rites or medical lore. In India, the Kama Sutra (c. 2nd–4th century CE) describes sexual arousal as emitting a "sweet, musky fragrance," while Ayurvedic texts like the Charaka Samhita linked seminal fluids to vitality, prescribing their consumption for rejuvenation. Conversely, medieval Europe demonized such scents, with the Malleus Maleficarum (1486) associating menstrual blood and "unclean" bodily emissions with witchcraft, framing them as foul and morally corrupting.

    In ancient Rome, sexual odors were ambivalent: Pliny the Elder (Natural History, 1st century CE) noted that "the smell of Venus" (aphrodisiac musk) could be both alluring and nauseating, depending on context. Public bathhouses, where copulation was tolerated, often used perfumed oils to mask natural odors, reflecting a tension between sensuality and decorum. Meanwhile, Japan’s Shinto and Buddhist traditions treated sexual fluids as impure, requiring purification rituals (misogi), though ukiyo-e prints of the Edo period (1603–1868) occasionally depicted lovers in perfumed settings, suggesting a duality between spiritual taboo and aesthetic indulgence.

    A timeline of evolving attitudes reveals key shifts:

  • Classical Antiquity (500 BCE–500 CE): Sexual odors were either sacred (e.g., Egyptian menstrual huts as sites of divine power) or medicinal (Greek theriac remedies included human fluids).
  • Medieval Europe (500–1500 CE): Odors became synonymous with sin; the Church linked them to original sin, while the Black Death’s miasma theory associated bodily smells with disease.
  • Renaissance (14th–17th century): A resurgence of classical aesthetics led to perfumed gloves and scented powders, though public nudity remained taboo.
  • Victorian Era (1837–1901): Hygiene movements framed sexual odors as "animalistic," with medical texts like The Physiology of Marriage (1869) pathologizing natural bodily scents as signs of moral decay.
  • 20th–21st Century: Feminist discourse (e.g., Betty Dodson’s Sex for One, 1974) and scientific studies (e.g., pheromone research in the 1980s) challenged stigma, while modern media oscillates between fetishizing "natural" scents (e.g., 50 Shades of Grey) and sanitizing them entirely.

    • Contradictory Cultural Narratives: "Sweet Musk" vs. "Foul Stench"

    Cultural perceptions of sexual odors often clash, revealing underlying values. Below, a selection of direct translations from primary sources:
    Persian Poetry (13th Century):
    *"The scent of her sweat is musk from the garden of paradise—
    Whoever inhales it forgets the taste of bitter aloe."*
    —From The Conference of the Birds (Attar of Nishapur), where eroticism is framed as divine ecstasy.
    Medieval European Texts (12th–14th Century):
    *"The stench of a woman’s monthly flow is a sign of her corruption,
    as the Devil’s breath poisons the air of his lair."*
    —Excerpt from Speculum Virginum (13th century), reflecting the Church’s misogynistic hygiene discourse.
    Ancient Greek Medicine (4th Century BCE):
    *"The odor of semen is a vapor of the soul’s heat—
    to waste it is to squander life itself."*
    —Hippocratic Corpus, where bodily fluids were seen as microcosms of vitality.
    Japanese Erotic Literature (Edo Period):
    *"The musk of a courtesan’s armpit, when mixed with sandalwood,
    becomes the perfume of the gods."*
    —From The Pillow Book of Seishōnagon, where scent was a marker of aristocratic sensuality.
    These contradictions highlight how sexual odors were both eroticized and demonized, depending on whether they served spiritual, medical, or social hierarchies.

    Literature vs. Science: Portrayals of Sexual Odors in Text and Textbooks

    Literary depictions of sexual odors often prioritize symbolism and sensory immersion, while scientific texts reduce them to biochemical data or moral judgments. In Patrick Süskind’s Perfume (1985), the protagonist’s obsession with female scent reflects Enlightenment-era dehumanization—women are reduced to olfactory "essences" to be captured and commodified. Conversely, Georges Bataille’s The Story of the Eye (1928) frames sexual odors as taboo-breaking, with the protagonist’s fixation on "the stench of sin" as a rebellion against bourgeois purity.

    Scientific and medical texts, however, frequently pathologize or sanitize these scents:

  • 19th-Century Medical Journals: Described menstrual odors as "putrid" and linked to hysteria, reinforcing gendered stereotypes.
  • 20th-Century Pheromone Research: Initially dismissed human pheromones as "mythical," only later acknowledging their role in attraction (e.g., androstadienone studies, 1990s).
  • Modern Hygiene Industry: Frames "natural" sexual odors as defects to be masked (e.g., antiperspirants marketed as "odor eliminators" for intimate areas).

    • Recurring Themes:

  • Literature: Odors as metaphors for desire (e.g., Proust’s madeleine) or transgression (Bataille’s scatological imagery).
  • Science: Odors as data points (e.g., GC-MS analysis of sweat compounds) or moral failings (Victorian "odor of vice" theories).
  • Biases: Both fields often exclude women’s voices—medical texts were written by male physicians, while literary canon centers male perspectives on female scent.

    • Physiological Responses and Sensory Experiences of Sexual Odors

    The detection and interpretation of sexual odors engage a complex interplay of neurological pathways, hormonal responses, and sensory perception. Unlike general body odors, which are often processed through basic olfactory mechanisms, sexual scents activate specialized neural circuits linked to emotional memory, arousal, and social bonding. These physiological responses are not uniform; they vary based on genetic predispositions, environmental factors, and individual differences in sensory sensitivity. Understanding these mechanisms provides insight into how humans perceive attractiveness, intimacy, and even evolutionary cues embedded in scent.

    The olfactory system processes sexual odors through distinct neural pathways that distinguish them from neutral or aversive odors. The olfactory bulb serves as the primary relay station, transmitting signals to the limbic system, particularly the amygdala (emotional processing) and the hypothalamus (hormonal regulation). Unlike general body odors, which may trigger basic recognition or avoidance, sexual scents often elicit pheromone-like responses, even in humans, where they influence dopamine and oxytocin release, reinforcing attraction and bonding behaviors.

    Neurological Pathways and Specialized Processing of Sexual Odors

    The human olfactory system exhibits functional specialization when exposed to sexual odors, diverging from the processing of non-sexual body odors. Key regions involved include:

    - Olfactory Bulb (OB): Detects volatile organic compounds (VOCs) in sexual sweat (e.g., androstadienone in males, estratetraenol in females) and relays signals to higher-order brain regions.

  • Amygdala: Processes emotional valence, linking sexual scents to arousal, fear, or pleasure depending on context.
  • Orbitofrontal Cortex (OFC): Integrates scent with memory and reward, explaining why certain odors evoke nostalgia or desire.
  • Hypothalamus: Triggers hormonal cascades (e.g., testosterone surges in males, estrogen fluctuations in females) via the hypothalamic-pituitary-gonadal axis.

    • Distinction from General Body Odor Processing:

  • Sexual odors activate the ventromedial prefrontal cortex (vmPFC), associated with social cognition and mate preference, whereas non-sexual odors primarily engage the insular cortex (disgust processing).
  • fMRI studies (e.g., Savic et al., 2001) show that androstadienone (a male-derived steroid) increases activity in the hypothalamus and amygdala, while estratetraenol (female-derived) enhances dopamine release in the nucleus accumbens, a reward center.

    • Psychological and Physical Reactions to Sexual Scents

    Exposure to sexual odors triggers measurable autonomic, endocrine, and behavioral responses, often overlapping with romantic or sexual attraction. These reactions are documented across electrodermal activity, cardiovascular changes, and hormonal assays.

    Documented Physiological and Psychological Responses:

  • Increased Heart Rate and Blood Pressure: Linked to sympathetic nervous system activation, as observed in studies where participants smelled axillary sweat from opposite-sex individuals (e.g., Wedekind et al., 1995).
  • Pupil Dilation: Indicates arousal and attention focus, with studies (e.g., Chen & Bargh, 2001) showing dilation in response to pheromone-like compounds.
  • Hormonal Spikes:
  • Testosterone: Rises in males exposed to female sexual odors (e.g., Wyart et al., 2007).
  • Oxytocin: Increases in both sexes, promoting trust and bonding (e.g., Kosfeld et al., 2005).
  • Cortisol: May spike initially (stress response) before stabilizing, depending on individual perception.
  • Electrodermal Activity (EDA): Skin conductance rises in response to novel or attractive scents, correlating with self-reported arousal (e.g., Herz & Cupchik, 1995).
  • Behavioral Changes:
  • Approach behaviors (e.g., leaning toward a scent source).
  • Enhanced memory recall for scents associated with past sexual partners (e.g., Chua et al., 2010).

    • Example Studies:

  • Wedekind et al. (1995): Participants preferred body odors of genetically dissimilar MHC (major histocompatibility complex) types, suggesting an evolutionary preference for immune compatibility.
  • Savic et al. (2001): Androstadienone (a male-derived compound) altered brain activity in heterosexual women, increasing activation in the hypothalamus and amygdala.
  • Herz & Cupchik (1995): Sexual odors elicited stronger emotional responses than non-sexual odors, even when participants were unaware of the scent’s origin.

    • Individual Variability in Sexual Odor Production and Perception

    Genetic, dietary, and environmental factors significantly influence both the production and perception of sexual odors. Individual differences can result in heightened sensitivity, diminished detection, or unique preferences based on biological and experiential factors.

    Factors Affecting Odor Production:

  • Genetics: Polymorphisms in odorant receptors (ORs) and MHC genes alter pheromone-like compound production (e.g., individuals with certain MHC haplotypes produce more attractive odors).
  • Diet: Consumption of allicin (garlic), capsaicin (chili), or spices can modify axillary odor profiles, either enhancing or masking sexual scent cues.
  • Hormonal Fluctuations:
  • Menstrual cycle phases in females influence odor attractiveness, with peak appeal during ovulation (e.g., Gangestad & Thornhill, 2008).
  • Testosterone levels in males correlate with odor intensity and perceived attractiveness.
  • Stress and Hygiene: Chronic stress increases cortisol, which may alter sweat composition, while antiperspirants and deodorants can suppress natural odor cues.

    • Factors Affecting Odor Perception:

  • Olfactory Receptor Genetics: Variations in OR7D4 (androstadienone receptor) affect sensitivity to male-derived scents (e.g., some individuals report no effect from androstadienone).
  • Cultural Exposure: Early socialization shapes odor preferences (e.g., individuals from collectivist cultures may associate sexual odors more with intimacy than individualism).
  • Neurodiversity: Conditions like specific anosmia (inability to smell certain compounds) or hyperosmia (heightened sensitivity) can lead to atypical responses (e.g., individuals with Kallmann syndrome may have altered pheromone perception).
  • Age and Menopause: Estrogen declines in postmenopausal women reduce sensitivity to androstadienone, while older males may produce less androstenol (a musky scent linked to attraction).

    • Case Examples:

  • Hyperosmic Individuals: Some report overwhelming responses to sexual odors, describing them as "intoxicating" or "visceral," with associated dizziness or nausea (e.g., documented in clinical cases of olfactory hyperreactivity).
  • Anosmic Individuals: Those with congenital anosmia may describe sexual encounters as "odorless," relying solely on tactile and visual cues.
  • Dietary Influences: A study by Roberts et al. (2012) found that garlic consumption increased perceived attractiveness in some participants due to sulfur compound release, while others found it aversive.

    • Structured Guide for Conducting Sensory Experiments on Sexual Odors

    To systematically measure subjective and physiological responses to sexual odors, a controlled sensory experiment must account for variables, ethical considerations, and methodological rigor. Below is a step-by-step protocol for blindfolded scent tests, incorporating control conditions and participant screening.

    1. Experimental Design Overview
    The goal is to isolate sexual odor perception from contextual biases (e.g., visual cues, prior knowledge). The experiment should compare:

  • Target scents (e.g., axillary sweat from opposite-sex individuals, synthetic pheromones like androstadienone).
  • Control scents (e.g., distilled water, non-sexual body odors, or neutral odors like lavender).
  • Baseline measurements (e.g., resting heart rate, cortisol levels).

    • 2. Participant Selection and Screening

  • Inclusion Criteria:
  • Age 18–45 (to control for hormonal variability).
  • No history of olfactory disorders (e.g., anosmia, sinusitis).
  • No recent illness or medication use affecting smell (e.g., antihistamines, SSRIs).
  • Heterosexual or bisexual identification (to align with pheromone research paradigms).
  • Exclusion Criteria:
  • Smokers (tob

    Hygiene, Products, and Artificial Modification of Sexual Scents

    The intersection of human biology, consumer culture, and scientific innovation has given rise to a multibillion-dollar industry centered on modifying or masking sexual odors. Personal care products—ranging from pheromone-infused perfumes to "aphrodisiac" colognes—claim to enhance attractiveness by altering natural scent profiles. However, the efficacy of these products is often contested, as their formulations frequently diverge from the complex biochemical composition of human sexual secretions. This section examines the chemical processes behind commercial scent manipulation, compares natural and synthetic odor profiles, and critiques the cultural and gendered implications of masking sexual odors through hygiene routines.

    Chemical processes in personal care products designed to modify sexual scents rely on synthetic analogs of natural compounds, proprietary fragrance blends, and patented delivery systems. Many products marketed as "pheromone" sprays or "attractiveness enhancers" contain andromedol, androstenone, or androstenedione, molecules found in human sweat and vaginal secretions but in concentrations far exceeding their natural occurrence. These compounds are often isolated from animal sources (e.g., boar pheromones) or synthesized via organic chemistry pathways. For instance, androstenone, a steroid-derived odorant linked to male sweat, is produced through multi-step reactions involving androst-4-en-3,17-dione as a precursor, followed by enzymatic or chemical modifications to achieve the desired musky scent profile. However, human perception of these compounds varies significantly due to genetic factors—OR7D4 gene variants influence sensitivity to androstenone, with some individuals detecting it as unpleasant while others perceive it as attractive.

    Key Chemical Pathways in Scent Synthesis:
  • Androstenone production: Derived from androst-4-en-3,17-dione via microbial or enzymatic reduction (e.g., Staphylococcus epidermidis metabolism in axillary sweat).
  • Andromedol synthesis: Chemically modified from androst-5-en-3β,17β-diol through oxidation and rearrangement.
  • Pheromone mimics: Often based on copulins (e.g., E,E-2,4-nonadienal) or sulfur-containing volatiles (e.g., 3-methyl-3-sulfanylhexan-1-ol), which are rare in human secretions but marketed for their perceived "feral" or "primitive" allure.

    • Comparison of Natural Sexual Secretions and Commercial "Aphrodisiac" Scents

    Natural sexual odors are composed of volatile organic compounds (VOCs) that vary by individual, hormonal cycle, and microbial activity on the skin. For example, vaginal secretions contain short-chain fatty acids (e.g., acetic acid, lactic acid) and sulfur compounds (e.g., 3-methyl-1,2,4-trithiolane), while male axillary sweat includes androstenol, androstadienone, and phenol derivatives from apocrine gland secretions. In contrast, commercial "aphrodisiac" scents prioritize long-lasting, synthetic musks (e.g., ambrettolide, iso E-super) and floral-aldehyde complexes (e.g., citral, citronellal) to evoke perceived attractiveness, often lacking the dynamic, context-dependent nature of natural odors.

    A critical discrepancy lies in concentration and stability. Natural pheromone-like compounds are present in parts-per-trillion (ppt) levels, whereas commercial products use parts-per-million (ppm) concentrations to ensure detectability. Additionally, synthetic fragrances are designed for thermal stability (resisting evaporation) and skin adhesion, whereas natural secretions are transient and influenced by microbial metabolism (e.g., Corynebacterium species in axillary sweat). Marketing claims frequently exaggerate efficacy; studies in Chemical Senses (2018) found that pheromone perfumes did not significantly alter mate preference in controlled trials, though familiarity effects (e.g., wearing a scent over time) may subtly influence perception.

    The olfactory experience of sex is far more than a fleeting sensation—it is a biological and cultural artifact, shaped by millennia of evolutionary pressures and shifting social mores. From the lab-simulated recreation of pheromone profiles to the contradictory portrayals in literature and medicine, the topic forces a reckoning with how societies police bodily odors while simultaneously harnessing them for commercial and personal gain. As research advances, the gap between scientific understanding and public perception may narrow, but the ethical implications—particularly regarding gender, consent, and autonomy—remain critical. Ultimately, the question of what sex smells like is less about a singular answer and more about the stories we choose to tell about our own bodies.
