What kind of fragrances are sexy, and why are they sexy? When thinking about sexy scents we think easily about the musk, civet and amber, the animal scents. They have a warm scent that reminds you of the warmth and smell of your own skin.
Animal scents have some similarity to human body odor. But we don't want to smell like body odor do we? We want to be clean and fresh but on the other hand we apply a scent that has some similarity to body odor, but in a different way. It's a subtle odor mixed with the most beautiful scents of flowers, fruits and woods.
A perfume that's made without some animal scents misses the warmth, it could easily smell like an air freshener it's as it don't fit or mix with your skin chemistry. A perfume made with some animal scents is like it's melting with your skin chemistry like the fragrance becomes one of your own.
The smell of flowers on the other hand could be very erotic as well. Some flowers have animal or body odor scents as well even if it is in small proportions. Like Jasmine has the aroma compound called Indole. But what someone finds sexy is also personal, some could like the soothing smell of vanilla for example, or just find the smell of fresh fragrances sexy because it smell like you just showered. Or what to think about sandal? Sandal has an aroma compound that is similar to the smell of the body odor of men Androstenol.
There are also perfumes with pheromones. Just as animals use scents to attract the opposite sex, we humans release pheromones and respond to the pheromones released by other people. Pheromones are naturally occurring chemicals in animals and humans which attract the opposite sex elicit sexual behavior. You can't actually smell pheromones but your body reacts on them. It's proven that people who have a smell disorder can have sexual problems. So smell is important for our sexual behavior.
I think that what someone finds a sexy smell isn't sexy for everyone. It's all about the personal memories, emotion, thoughts and gender. The most sexy perfume to me is Must de Cartier, what is your most sexy fragrance?
