<human>: Could you distill the essence of the text into 1-3 sentences?

I've been with this girl for 2 months now and I really like her, we share the same interests we get along well and frankly I think we make a good couple but recently I found out about her sexual past and it's been nagging me, I asked her about her sexual past after two guys texted her asking for casual sex when I asked her she told me how she's been with a lot of guys before, I don't know the exact number (I've only been sexually involved one girl before her) and she said she didn't respect herself back then and that she's not proud of her past, I trust her and I don't think she'll cheat on me but the fact that she is so much more experienced than me and the fact that she would have casual sex on a constant basis with different guys bothers me a lot.

 I'm falling for her but I don't know how to get past this, she is constantly telling me that she loves me and that she can't see her life without me that I am the one and that she wants to marry me one day but I feel like it's too soon for her to say those things and all she really wants to do is to settle down with me, I feel like it's not fair for me because I really haven't experienced as much as her and I don't really now If she is right for me. I'm confused maybe I'm just being selfish. What do you guys think?
<bot>: My girlfriend has slept with many guys in the past and It bothers me she's also talking about marriage too soon. I like her a lot but I need some advice.
