Pheromones are the smell of sex.

Pheromones are odorless and therefore can only be perceived unconsciously. In addition, these substances - as shown by previous studies - cheer up the opposite sex. It is also interesting not only that such signaling substances directly affect people's sexual perception, but also the fact that the human nose is able to independently perceive the difference between men and women. In addition, sexual orientation plays a role in the perception of pheromones. The study showed that homosexuals respond to same-sex pheromones.
