I have a problem that I don't know how to solve. I was with a guy I met few hours ago and I find him good looking, he was looking around for someone his type so I saw him in the room getting penetrated from another guy I went inside the room and he started to suck me I had an erection for few seconds and it was gone I wanted to penetrate him but I could not do anything about it
If I was alone with a guy I will have a normal erection for a long time with no problems

I am a healthy 22 years 114 pounds gay male and I need to know how to solve this problem
