I must have been about 12. Somehow, i got curious about seeing what it would be like to hold my dick under the bathtub faucet as it was filling the tub up...i don't rmemeber if i was hard or not before sticking it in strong flow of the water, but i certainly remember being hard when i stuck it into the flow. It felt incredible, and i experimented with the water temperature and cold got me super hard and turned my cock head purple! The first time i did this,i remember having this sensation, after a couple minutes of being convulsed..there was something going on that made my dick super sensitive, and then this rush of something...i didn't know what...lol. All I know is that i returned to the tub often and spent lots of time taking baths after that. That bathroom was on the second floor, and i remember looking out and seeing a shirtless man in swim trunks washing his car..he was tan and muscular and a bit hairy...he must have been in his mid twenties, and looking at him made me very hard...hence, I'd take a bath...:) I eventually figured out that I was cumming, though I had never heard that world and didn't understand the concept, and don't recall associating it with sex for several years. I've always been attracted to mature men..a twenty something was certainly that back then. I'm in my early 70s now. Still love mature guys...
Probably about 12, started sneaking out of my PJs when I was 10 and the sheets on my naked body felt great. One night I woke realizing I was enjoying rubbing (humping) the sheets,,, felt so good. No idea what was happening but knew I enjoying it. Then when i realized i was cumming I switched to socks so my mom wouldnt notice the sheets.LOL
