My First Official Encounter

2 weeks after my 13th birthday, my folks sent me off to a 2 week retreat. I was by far the youngest person there. I'd say the rest of the folks were 18-30 and there was probably 12-16 other attendees.
Everyone was nice and we had a large barrack like set up for our beds. It was late summer in a suburb of Calgary and one night we were told there was a tent set up if we wanted to sleep outside. I must have agreed to go and there was at least one other guy in the tent with me. I went off to sleep, but woke up in the middle of the night with my sleeping bag unzipped and one of the males in the tent sucking my 13 year old cock. I only remember that this guy's hair was curly. I put my hands on his head and pushed him away before putting my cock away and turning away from him as if I was still asleep.
I blocked out the rest because I don't remember who it was. I don't think he continued after that, but again, I may have blocked it out.

I don't know if it impacted me sexually or changed my sexual trajectory. It probably did. About 15 years ago I tried gay sex, mainly sucking and being sucked, but eventually fucking and being fucked. This was because my wife of 20+ years has lost her interest in any form of intimacy.
