I'm a college sophomore, and I have this mental gap in terms of hooking up with really attractive girls that I know 100% want to have sex with me. The reason for this is that I'm relatively inexperienced and don't want to leave them thinking, "he wasn't that good." As a particular example, there's a group of close friends in my year that I know somewhat well and almost all of them are drop dead gorgeous. I know that at least three of the girls find me really attractive and would want to hook up (and I'd also be down) with me if I made a move, but I've avoided it because I don't want to sleep with one and then have the rest be told "he sucks in bed, not worth it." Do I have it all backwards, i.e. is this only compounding the issue? / am I completely alone in this?

Thanks!
