Axilism. The armpit, this small hairy area, plays an important chemical role and reflects a major change in the sexual habits of the human species. When our ancestors mated, with the female on all fours, the armpits were away from the partner's face. When we later assumed an upright posture, men and women began to predominantly adopt the frontal sexual position, with the nose being close to the shoulder region. And there were the armpits, the ideal place for the development of sweat glands. Its presence is exclusive to the human species, in both sexes. The aesthetic attraction of the region can be associated with affection, such as caressing, licking and even kissing. #Axilism
