The pupils of men and women dilate when they see someone or a photo of someone that they find attractive. This held true with gay persons concerning same sex attraction. In addition, observers tend to find people with dilated pupils more attractive. This is one of the reasons women tend to wear eye makeup, to draw attention to their pupils and this in turn is perceived by many as attractive. Torso movements also say a great deal about men and woman.
Humans do a mating dance comparable to animals and insects.
A woman talking with a man she finds attractive will lean forward with her arms at her sides and squeeze her breasts together, enhancing her cleavage, or cross and uncross her knees at the knee. Hand movements say much about a person and can be associated with sex or ethnic group. Fluttery hand movements are associated with femininity and are one of the tools people use to find out if someone is gay. However, in the Italian and other European cultures talking with hands is not only acceptable but also part of the enjoyment of being engaged in conversation. On less enjoyable terms, many obscene hand gestures also have been adapted from all over the world into our society and are employed usually as a parting shot before walking away from an opponent.
