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

I've been with my current girlfriend for over 2 and a half years, the last year of which as has been long distance. We have a great relationship; our personalities are perfect for each other, sex is great, the distance is hard but we make it through by staying positive and imagining our lives together after the separation is over. There's just one problem: I'm really insecure about her being around other guys. I do trust her and I know she would never cheat on me, but I get uncomfortable when she goes to a party with other guys or hangs out with her guy friends. I thought this was an issue that would solve itself over time, but it hasn't. I suppose I should mention that I accidentally stumbled upon conversations she was having with her friends where she discussed how attractive she found some other guys(including some of my friends), but that happened months ago and we have handled those issues. I'm afraid that my insecurity might end our relationship if I can't control it. I really want to do anything to solve it though because everything about our relationship is perfect for me.

I was wondering if any guys out there have had similar problems with insecurity and if so, how did you get over it?
