Not a word. I was fully masturbating years before something came out of it, so it was "been there, done that", long before he might have thought to have the talk. In fact, Guys in the group couldnt wait to be the one to share that he had finally "made cum". Sometimes, we'd have to prove it. LOL. There would have been two things that I would have appreciated hearing from my father...Don't feel ashamed for doing it AND when you do do it, take your time, learn to edge, appreciate getting there, don't rush it. Maybe the latter, might have reduced my PE, later. It was always about the quick, instant gratification. That advice could help a lot of guys.
