What do i do?? Help please!!?

So I been on a few dates with this guy and he's really hot. Every where we go all the women check him out, waitresses flirt with him, etc. Of coarse, he says he's not interested. at first, I felt kind of lucky to have a man that every one else wishes they had. But, now I feel a bit worried that if I don't satisfy him then can pretty much have any girl he wants. What should I do?
