I don't believe when my girlfriend says she has never had a boyfriend before me, is it possible?

So I'm really happy with my current relationship, I love my girlfriend, but I can't get a thing out of my mind, I know I should trust her and I do but I find it hard to believe that she never had boyfriend. At first I though she was joking, but she keeps insisting.

My girlfriend is really gorgeous, the kind of girl that makes everyone stop and stares, it drives me crazy how much guys drool all over her.

And she's also very out going and always speaks her mind. So I don't understand why?

Can someone give me legit reasons

I want to understand her better.
