My girl discovered self-pleasure at the age of 5, ironically during an exam from her doctor (she doesn't think it was intentional). I had an ex discover masturbation around the same age. I personally discovered it around 11 or 12. All of the above discovered porn accidentally as kids. I don't know about them but after that I intentionally sought it out.

Guess what! Both of us are perfectly fine!! (Well the ex is a bit psychotic but that's unrelated...)

This obsession with protecting kids from the realities of life is just fucking stupid. We as a species have the stupidest, most ridiculous views about something that is required to keep us alive!
