Two can play that game!

People consider it the "norm" for men to date multiple women, but when women do it, they are considered as "loose" and a whore. There are some women who actually enjoy being single, and free to go out with/date multiple men. For a woman it doesn't always have to be about sex. But the delima that I'm faced with is...is it okay for a woman to have sex with a man she has no intentions on building a relationship with? Is it okay for her to simply want the sex?
