Doesn't it sound popular to be wild? having sex with all those men you hardly knew? But ask yourself, what were you trying to communicate? ...uhm...to yourself...?
Was it like : wow, look at me I'm worthwhile?

I think you are chicken out on your current boyfriend. If you want sex you know how to get it. However, what you are afraid of is intimacy. And please don't blame the lack of sex on him. Sex is a mutual thing.

Intimacy is something that goes along with sex. It might give you just that final touch to enjoy sex fully. Girl, this boyfriend sounds like a stayer to me, so try him out how deep your feelings dare to go.
