<human>: I'm a late bloomer.  I went through puberty when I was 18, kissed my first girl when I was 21.  I never got that much attention from the opposite sex until I recently started coming into my own.  

I started dating this girl about a month ago.  We've been on 7 dates and we've always had a great time.  On Saturday night it became apparent things were going to get physical, so I decided to be honest and let her know I was a virgin.  This threw her off a little and she decided to tell me her number ...19. Oh.  I was surprised but I didn't let it bother me in the moment.  It happened.

I really don't want it to bother me but I can't get it out of my head.  I don't know what to think about her anymore.  How could I marry someone who's been with that many guys?  If we have no future what's the point of dating?

At the same time I feel like I'm being immature.  Who am I to judge someone's past?  Shouldn't the only thing that matter be how she feels about me?

I recognize that I'm being stupid but I can't help how I feel.  I just don't know if I should continue to see her and lead her on any longer. 

Advice?

Can you condense the text into three sentences or less?
