I started dating my current girlfriend a couple of months ago, and ever since I met her, there's something that disturbs me about her past. She's 3 years younger than me (I'm 21), and has a very "colorful" past, with more less twenty sexual partners on her account. We've gone over this a few times before, and though reluctant to talk about the subject, she's told me as much as I think she's ever going to tell me: that she didn't feel loved at the moment, that she slept with these guys because she felt loved that way, and that she's ashamed of her past.
As for me, I dated a single girl in the past, I didn't have any sexual experiences whatsoever until now, and I have the feeling that I would've wanted to have at least another experience. And since I won't be cheating on her, I feel in quite a difficult situation.
I really love my girlfriend and feel trully happy with her, I won't be dumping her for such a thing. I know that what's in her past cannot be changed, and I certainly believe that it's not worth worrying about that at all, but I cannot seem to change my mind. I've been always insecure and I've had a very low self-esteem in my past (the main reason for my lack of experience). What do you think that I should do to overcome my feelings and accept her past?
