Can you be sexually attracted to someone but not want to have sex with them? Or does that mean that you're not actually sexually attracted to them?
I could be wrong, but I think you have to at least like the idea of having sex with them. For example, if you see a cute guy on the streets you may say "well I wouldn't want to literally have sex with him since I barely know him and I'm waiting for marriage....but damn He's hot and if he were my husband, I'd do him all the time". Otherwise I think It's more of a platonic physical attraction, like how lesbians are sometimes aroused by two men having sex but don't have a real sexual attraction to the men.
