My girl has too many exes and guy friends

I've been with her for over 11 months now, at the start of the relationship she lied to me about how many guys she dated and had sexual relations with. But now I discovered (she told me after stories didn't correlate) that she has had sex with a lot of guys 55+. She also cheated on every one of her previous boyfriends. She was a heavy smoker, drinker and drug user too. Since we started dating she dropped the smoking, drinking and drug use. She assures me that she has changed and will never go down that path again. But even now she maintains contact with some of her exes (though they're in another country) because "they could be useful". She also has a lot of guy friends. In particular this one guy was on the phone with her and wanted to skype, she said she was naked and he replied "it's not like I haven't seen you naked before". And they proceeded to Skype (she covered up though). She claims "he is just like a brother". The conversation was very casual though. I have been finding it difficult to deal with her true past identity, and I do want to be with her. I am a pretty conserved guy with less and 10 sexual partners. And it's just hard for me to deal with all this. I do not want help, I just want opinions. Thanks :)

Sly, only you can decide how to deal with your Gf's past. You choose to be with her and therefore you need to accept her totally for you guys to work out. By the sound of it, you guys are chalk and cheese. It's all good to be in contact with exs as long as you're in the picture and the exs are GENUINE and have respect for you and your relationship with her. If she's upfront with you about cheating in the past, then you need to be wary because cheating is either in us or it's not, never mind the circumstances. We'll either do it or we won't. The old saying goes, (but not necessarily true) once a cheater, always a cheater. And you're not alone here Sly, because most guys would find her past, as you describe it, hard to deal with, regardless if their past was similar to hers or not. Take a heads up about her previous drinking/drug habits, they can be pretty damaging and it gives you a clear picture of what she's really like and the environment she has come from. Sky, you also need to realize, that her past shouldn't really matter if you are compatible and happy together. It's a common mistake (and made far too often) to delve into our partner's past because we need to accept them completely just as they are in the present.
