I need some advice on what to do with a friend. I've been thinking a lot about hooking up with a friend of mine. I've had some experience with guys in the past and want to continue exploring. About a year ago I went to a party with my friend Sean, we got really drunk. As the night was ending we decided to go back to my place, since it would be a shorter cab ride. Once a my place we kept drinking and passed out on the couch. All of a sudden I felt a tickle on my arm. I woke up and realized Sean was passed out next to me and went back to sleep. At this point I was still drunk and half asleep. Next I felt something on my arm again so I didn't think much of it until I felt Sean grab my arm and putting my hand down him pants. I pulled my hand out but he grabbed it and pushed it down his pants again. To make a long story short he stuck his hand down my pants and we jerked each other off. I was surprised but ended up liking it. Since then we never talked about or mentioned it.
Since that night I've been thinking about hooking up with him but don't know how to do it. We are both open-minded and outgoing but don't know how to initiate that conversation or how he would reacte. He has been my friend for two years and has been a friend that l can go to for help. So my issue is that I don't want to ruin that friendship.
At this point should I bring up what happened the other night? Should I initiate going further? If so how? I have a million other questions but I'll leave it there for now. I thank everyone in advance for the help and can give more if needed. Thanks again!
