Looking For Some Info.

Hi, i'm a 21 y/o male. Recently I have been spending alot of time with this girl that I have liked for a long time. One night I was drunk and one of my hands went wondering. In and around her genital area I felt little bumps.I don't know if it is something to be worried about or not.I have been with more then a few partners. But she has only been with two.I recently just got done getting tested at the doctors like two weeks ago. I go like every 5 - 6 months to get my blood work done and he also test me for stds.I tell this girl everything,she knows how many partners I have had, and she knows I get tested every so often,but I don't know if she has ever been tested before. And I don't want to embarrass her by talking about the bumps.I guess what i'm trying to say is it normal for some girls to have bumps without them having some sort of std, if not does anyone know what this might be??I really like this girl and I do want to be with her.(not just sexually) even if the bumps are something bad, that won't stop how I feel about her.
Any info or insight is much appreciated.
