About a year ago I started dating my current ex. We were introduced by his cousin, my best friend. Let's say that my ex is R and his cousin is A. While R and I were dating, I would get really horny a lot and he'd talk dirty to me, but I never really got turned on by him. I didn't want to lose my virginity until I got married bcoz I have morals, so we kept it strictly at that. But A had always been very sexual and vulgar, and he was apparently attracted to me and would try talking dirty to me even tho he has a gf. I don't think he was dating her then, but I'm not sure. I would tell him not to at first even tho it really turned me on, but as time went by I would start talking dirty back to him. He just knew what to say make me wet, and I really liked being turned on by him and I would masturbate thinking about what he said he wanted to do to me... I felt kinda guilty about it tho bcoz R was a really good bf, but I never told him n I never really stopped. One day tho, R hacked into my Facebook and saw some msgs that we're goin between me n A n he went totally berserk. He and A were fighting for a while, but after a while things cooled down. Even tho R was a good bf, I just found myself being less and less attracted to him and eventually I broke up with him. It went really badly, and as A was my best friend, I went to him. He and I are exactly alike, so I talk to him about everything, and when he talked dirty to me we just talked about more things. I hide nothing from him. Soon, I started falling for him. By then, he had his gf who I was extremely jealous of bcoz I knew A would never choose me over her. R and I would talk as just friends, but he constantly brings up wanting to be with me again and I got tired of it and a couple of weeks ago I told him I needed a break and stopped talking to him. I think about this a lot and I feel kinda guilty....
