Erogenous Zone - Armpits

Armpits

Some consider the armpits to be an erogenous zone. If pheromones exist for humans, they would likely be secreted by a mixture of liquid from the sebaceous glands with other organic compounds in the body. George Preti, an organic chemist at the Monell Chemical Senses Center in Philadelphia and Winnefred Cutler of the University of Pennsylvania's psychology department, discovered that women with irregular menstrual cycles became regular when exposed to male underarm extracts. They hypothesized that the only explanation was that underarms contain pheromones, as there was no other explanation for the effects, which mirrored how pheromones affect other mammals.
