LuckyGuyKC saidI have been asked by male masseuses if I would like more than a massage (I find that incredibly creepy since you are nude and in a prone position) .... I see this as prostitution. I was asked by a very hot graduate student five years ago if I could "take care of him" after we had sex a few times (I suppose as sort of free sample because the sex stopped immediately when i declined) .... I see this as prostitution.
So paying someone to make you feel good by rubbing all over your body isn't prostitution. But if they make you feel good by rubbing your dick, it becomes prostitution then? Seems like a slippery distinction, when most people sell their bodies in various ways to make money.
I couldn't do it though, the risk of catching something greatly outweighs the potential income. That and the obvious social stigma revolving having sex for money, even though nobody really has a problem when someone sleeps around for free.
To answer the OP, I have no idea if it's more prevalent or not. I've never met a guy looking to be taken care of, though I have had a guy offer to "take care of me". Tempting offer, but he lives several hours away haha
