Please help? Answers!?

Ok, I don't want this to sound wrong, so don't take it the wrong way, but I am confused. I literally have an entourage of guys who follow me everywhere and chaffeur me and buy me stuff and call me all the time. Yet I never have dated any of them. I'm a nifty person :) and I'm attractive but I'm no jessica simpson. Why do these guys do this? And how come, if they like me so much or whatever, they don't ask me out? The thing is, I don't consider myself a slut and I don't act that way, but they all tease me about it even though I don't ask for it AT ALL.
