It started in the crib, where I discovered that laying on my stomach, & kicking my legs felt good. Real good. The more I did it, the better it felt, and it would build up to an explosion of pleasure. The first few years of my life I was masturbating without even knowing it. I did it all the time, anytime, (when I was bored, stressed, angry, happy, excited, etc.) and nobody knew what I was doing, including me. Used to do it with the family watching TV in the living room. As I got a little older, and my folks started figuring it wasn't right, I had to do it secretly. Discovered at a young age that pics of girls worked best, and enhanced the hell out of the experience, but still never knew what the hell I was doing. Did it for years...and it wasn't 'til it was accompanied with some mystery goo that I figured I'd find out what's going on. Didn't think I broke anything, because there wasn't blood, but definately something was up.

Got caught so often while doing it, that it never seemed like an option to do it manually, as it would be more embarrasing to be caught with my pants down. The floor method allowed for doing it clothed. The goo presented a minor challenge easily overcome with tissue or an old sock stuffed in my pants.  Didn't do it manually 'til my 20's, when there was more reliable privacy. Did it floorstyle well into my 30's, but then switched to manual, although it isn't as quick or clean.
