Sexual Jelousy Men are more concerned about female adultery than vice versa because they can never be sure that the child she is carrying is theirs. Selection has favoured male adultery. Symons suggests jealousy may be innate in men but learned in women as a response. It is only men who court, woo, propostition and give gifts for sex and only men rape. Men stand to gain by copulating with any available woman.
Sex is something that women have that men want.
Sexual pleasure Men generally are thought to have more sexual pleasure than women. The more pleasure a woman has, the weaker her bargining position. This does not make any difference in sexual economics as women have less drive but the capacity for multiple orgasms. Men have more drive but less stamina. Visual arousal Men are aroused by pictures and sights of women - as discussed before.
