Nothing wrong with only wanting sex for a woman or a man. Married people call it making love. Sex is sex married or single. As far as men are crockpots and women are microwaves is a joke. I've been with women in their twenties who were worn out after a few hours and women in their fifties who could go all night long. Age has nothing to do with sex drive. A man and woman can have sex and just be friends. Why not. What's wrong with having fun together and hot sex together. Of course love complicates things. But women fall in love with men just as much as men fall in love with women. Old saying you can't live on sex alone and you can't live on love alone. For married people I'd agree but for single day why not. Jealousy is what ruins relationships and marriages.
