So I used to be dating a girl I really like, we had been going strong and it was become my first good relationship. Eventually we had gotten pretty close and I started to sleep with her but then she start to talk about how she used to have one night stands on a weekly basis and that she had been with guys much older than her at a young age. For me this was a major turn off. We aren't together anymore but I was later told that she could've just been lying to show off? Could that be true?
