I was out clubbing with 3 friends (an engaged couple and a single female) and with a night drinking and all the loud music me and the guy and me make out, at first I thought that "fuck this is gay and his girl is gonna kill me" but it didn't bug me or his fiancee (oh they are both bi it is a heterosexual couple). What I later found out that it really turned her on. I'm comfortable enough with myself to make out with a guy and not feel much but that's not how the night ended. The other girl was getting drunk and the couple was already turned on as hell and all we had to do is mention sex and the other girl was for it. We left the club and on the way to the nearest hotel the guy got to work on me while I was driving (most sober one apparently lol) and was giving me a blow job (incredible feeling while driving haha) and his girl was working on the other girl. We got to the hotel and got a room, and we all got naked and well you know got shit started at least that's what I thought. I was going back and forth between the girls eating them out and the engaged couple took turns going down on me. The problem was that sometime after that i don't know what happened but I couldn't get it up, I never even came. I only got hard after everybody fell asleep I don't know if it was the drinking or the fact that that sexual experience was my first true experience or both of those things. Anybody have any ideas why? And anything to do if it were to happen again?
