Sexual Attraction and Attractiveness: The Science Behind Chemistry Between Partners
Explore the science of sexual attraction, pheromones, and hygiene tips that support confidence and intimacy.
In short: Attraction between partners depends on the senses: touch, sight, hearing and smell. In animals, chemical signals called pheromones influence behaviour; in humans their role has not been proven. Although attraction happens without our being aware of it, it is helped by personal care: cleanliness, bathing, dental care and perfume.
Sexual attraction and attractiveness to others is a fascinating and complex topic. Many factors play a role, including social, physical, and anatomical elements that all contribute to how we experience attraction.
- Tactile senses: play a major role through physical contact.
- Visual stimuli: well known to have a vital role in sexual arousal.
- Auditory stimuli: have a smaller effect, such as listening to certain kinds of music.
- Olfactory stimuli: it is well known that unpleasant smells can act as an inhibiting factor, but pleasant scents can act as an exciting sexual cue.
Pheromones
Pheromones are chemical substances secreted by one person and received by another person of the same species, which can stimulate a specific reaction.
The changes of this period in a girl’s life are described in our article on puberty in girls.
This remains an exciting area of research, and many of its applications are still being studied, with several points still open to scientific debate.
That said, although several candidate substances have been studied, no human sex pheromone has yet been clearly identified or proven to change attraction or sexual satisfaction, so products sold as ‘pheromone’ perfumes or sprays are not proven to work.
Whether in same-sex or opposite-sex attraction, pheromones are thought to play a role in these preferences.
Many of us notice that when we are attracted to someone, we often love the natural scent given off by our romantic partners or potential mates.
Many women who live or work closely together feel that their menstrual cycles become synchronized, but careful scientific studies have not confirmed this; the overlap is most likely due to chance, since cycles vary in length.
Scientists have proposed that body odours carried in sweat and skin secretions may subtly affect mood or attraction, and pheromones in animals are grouped into types such as releasers and primers; whether similar effects occur in humans has not been proven.
Pheromones do not only play a role in attraction — they may also have no effect, or even create a sense of aversion. These reactions are not always mutual: you might feel drawn to someone’s natural scent while they feel nothing in return, or occasionally the opposite. These responses tend to happen below our conscious awareness.
So while attraction often feels like a mystery, it is not entirely unexplainable — there is real science behind these subconscious signals.
Personal hygiene matters for both partners — it helps you feel fresh and confident, which can reflect positively on your relationship.
A few tips that can help:
Shower or bathe before bed.
Brush and floss, and freshen your breath.
Shave or trim body hair if you prefer.
Use perfumes and lotions that feel good to you.
Genital area appearance matters too:
The size, shape and colour of the labia vary greatly between women and are almost always normal. Some women choose surgery, for example labial reduction when large labia cause discomfort, irritation or distress, after careful counselling about the benefits and risks; labial fillers are also offered, but their long-term safety is less well studied.
[Darker skin in the genital area is normal and is not a sign of poor hygiene. Lightening treatments are available, but they should only be used under medical supervision, as some over-the-counter creams contain harmful substances such as mercury or strong hydroquinone.
