First wet dream was in 7th grade… so that’d be what, age 13? I have to assume first erection took place some time before that, but it wasn’t a memorable enough experience for me to actually recall…
@Mr_M I’m picturing the scene from Pleasantville, where the Black & White jock is in a car with the Real girl, clearly about to have sex. He suddenly stops and looks down, horrified, saying “I think something’s wrong!!!”. She looks at him, looks down, looks annoyed, and says “Trust me. That’s supposed to happen.”
The first i can remember was a day after class in the 6th grade… our religion teacher told us about “the evils” of masturbation and self gratification… we had no idea what she was talking about… and curiosity won out… so i guess around 12-ish.
My little guy has said “Daddy, why is my penis sticking out like this?” Usually this resonates through the house, since he has no volume control and has the bathroom acoustics working for him.
