When I was about 12, I was with a "girlfriend" of mine in her room. It was a typical "little girl's" room of the time with pink walls, rainbows, unicorns, etc. Her parents weren't home and so we started getting into the "you show me yours & I'll show you mine" thing (actually we were daring to show each other how much pubic hair we each had)
She finally relented & opened her pants first & it was the first time I had seen a real girl's pubic hair. Obviously, there was no way I could show her my hair without her seeing my erection. I started to stroke & said something like "watch this" then came in front of her. She started in with saying "oh that's gross" & stuff & carrying on. I felt a bit embarassed but couldn't help myself.
Anyway - that's my wildest (wierdest) place - in a pink girl's room with horsies and rainbows
. Haven't top it since.
