I did it twice, i was with two friends and one of the friends parents on a sailing trip. Me and my friends were bathing in shorts but his dad said we were sissys and jumped into the water naked. I said we should try it but they disagreed so i dropped my shorts and dove into the water. Then i realized there were two girls looking at us from another boat and it got awkard for me... Especially as i had about 1" flaccid penis back then, haha! Then we did it all three of us friends later because i said it felt great. We also masturbated together and were showing our cocks to each other. I was maybe 3" hard at the time and they were about 5" and 7", but they understood i was really late into puberty and said "hey itll grow for you too, dont worry. Mine grew very fast as i got into puberty". It was a really fun trip overall, i remember the face of my friend when i told him he had hair in his ass! I noticed when he dropped his pants and "mooned" me, haha. He said "WHAT?!" and we laughed. We did lots of fun stuff! It was great,, too bad he moved a year later.
