Who would say? Male orgasm depends not only on the attractive appearance of the partner

Excitement and sexual satisfaction of men depend not only on the sexual partner's appealing appearance but also on the character of relationships, says a study in the Archives of Sexual Behavior.

Scientists at Queen's University, Canada, have studied the sexual behavior of heterosexual men in the 18-40 age bracket, the study said.

Specialists measured participants' erection while the latter listened to 18 audios simulating sexual contact with different partners: friend, unknown woman or permanent sexual partner.

The scientists evaluated the reaction of men according to the Kinsey Scale, used to describe the sexual orientation of people, and came to the conclusion that the excitement and intensity of the male orgasm tend to be greater during casual or permanent sexual relations. It is worth mentioning that relations of friendship with a woman diminish both men's libido and subsequent sexual satisfaction.
