<human>: Condense the text into a few key points

Never posted here before so please let me know if I do something wrong, I just want to be honest because I need so much help right now.

I've been dating my girlfriend for a few months, close to 8, and we are both in college. I really do love her and she is completely amazing. Really smart and sweet, we share a lot of similar interests and she is a great writer. She is absolutely gorgeous, legitimately 15/10. I am also going to mention that she is the most unbelievable sex partner I could have imagined (don't think I should go into much detail here but if I need to explain tell me) . 

We felt comfortable sharing everything between us so we had the 'sex history' talk. I have had only sex with 3 girls and she has been with 13 guys. Ever since I found that out a few days ago, it's been eating away 
at me. I have this urge to just know all of the information. How did it happen? Who were they? What did they do? 

I'm thinking about confronting her and asking about it when she gets here later, but I don't know if this is a good idea. This seems like its completely my problem and not at all hers, but I need to know. At the same time I don't want to ruin what we have. I am going to do it soon because I don't think I can keep waiting much longer without bringing it up again and being awkward or go on without actually finding out.
<bot>: GF told me about the guys she's had sex with. I think I'm going to ask her more but I don't know if I should
