I had to respond to this. I have the same situation on and off for about 8 years with my best friend.
I was completely in love with him. We began to do things too when drinking. He started it. The first time he started stroking his Dick out side of his pants when I was messaging him. I sucked him off he said thanks and went to bed. He got very weird the next day we had gone out to the gay bar for kybirthday where he picked a fight with a guy who was looking at him. Go figure trying to prove his masculinity.
We started doing things again a few months later, me sucking him off. I finally brought some jerk off toys into it, different lube and things. Finally I started fingering his ass which he loved and will never admit it. Finally after awhile I felt used and I wanted to be loved so bad in return. This whole time I thought he was just getting comfortable and would eventually start loving me.
He started tucking girls and i was devastated. I cried everyday for weeks. It hurt me so very badly.
Then he would come around again, tell me they broke up and he could never get off with them like he could with me. Stupid me, I sucked him off again.
During this whole time of him wanting it he would turn at times and say I took advantage of him because he was drunk. I was floored. If anybody was being taken advantage of it was me being used.
But it continued. We would be on then he would freak out and not talk for months. Come back apologize and start things up again.
Finally he said one night. I want to know what its like for gay guys, dropped his pants and wanted me to fuck him. I was Sooo nervous I couldn't get a full on erection. But we fucked for a few minutes real slow. Then I got on top of him and road his cock. It felt wonderful!
That was the last time anything happened. We remain friends and he is actually living with me for a ear now. I have set my feelings aside to remain friends. It's been working out. I never regret what we have done, if he offers im on it. Knowing what of only will be.
Lately he has been bringing up what we have done, especially the ass, I think he is wanting it again. Has to be his idea, I will not be responsible.
That's my story, if you can separate your feeling.vs, then have fun. If not, you will be heart broken when he is done using you. And it hurts very very bad. Be careful, have fun and when you can't stand the lack of love and emotion, get out for your own sanity. If you get heart broken, you will heal in time, don't do anything crazy. Surround yourself with people who love you.
