Why doesn’t a man say to a woman that he wants to insert his penis into her vagina and thrust until he ejaculates? Firstly, women are hugely offended by any mention of the genitals of either sex. Women make themselves attractive in order to enjoy platonic admiration from men. Secondly, women are looking for an loving relationship, not sex. They generally only offer regular intercourse to a man who is companionable and demonstrates caring behaviours. This is the function of dating and romance.
