By Accident
I started masturbating about four years ago (or something like that). I do it pretty often. The first time I ever masturbated, I was looking at dirty sites when my folks weren't home (hehe). And all of a sudden, I felt like I was gonna piss. It felt kinda of good. It took me a while to actually learn how to do it. I got hard almost everytime I thought of a naked girl (which was pretty often). The first time it just sort of happened. (I didn't really stroke my dick or anything.) I found out what it was called from a book (that I was looking at naked girls in), and I love it. And now I just do it all the time.
