I was 22, she was 17. She was the friend of my friends younger sister.
She wasn't a virgin. In fact I found out a couple months after we had been sleeping together that she slept with my best friend (also 22, not the friend with the sister) while I was on vacation. Apparently they had been sleeping together for a couple months before she started sleeping with me, but then they stopped speaking which is when we started seeing eachother. Then I guess they started speaking again while I was on vacation.
I talked with my buddy about it and we were never both sleeping with her in the same time frame, once I got back from vacation and found out (found evidence of her being in my buddies room) I cut all ties with her. Neither of us knew she had slept with the other one until I found out. I thought shit like that only happened on 90210 haha. Probably should have expected it though I guess with her being 17. I'll probably just stick to girls my own age now.
