Women nature all arranged differently – their genitals covered with vegetation in the form of a triangle of pubic hair that attracts men's attention and excites them. Men, in turn, pubic hair emit pheromones, which also serve as a stimulant and can cause a hormonal response in women, even at a great distance.
