My similar post to a similar thread about two years ago:
I was about 7 and sent off to a summer camp. First or second night, big group showers (supervised) for all campers so 6-7 year olds thru those just hitting puberty. First shower....just about everyone hard a hard on. What a newly discovered mix of different bodies, colors, cocks. Next few nights (I was there two weeks) our newfound erections were gone but I was able to do plenty of looking and realized I was anxious to see one or two of my camp friends in the shower naked.?
Also a shocking thing for me....my first BBC ?
