I voted 10-15, but I don't really remember. I know I was too young to ejaculate, and it actually started by accident in the shower. Then somehow I discovered that I didn't need the shower, and my fingers worked just fine. The first time I DID ejaculate, I thought I had injured myself. Then I found out that my dick wouldn't fall off, and I still REALLY wanted to do that again, and life was good.
I was doing it before I had any idea what it was that I was doing.. I did know that I shouldn't be doing it in front of other people though, so that was good! I was probably 7?
My boyfriend had a similar story.. when he was younger he realized how good hot tub jets feel lol. He thought it was great, until someone caught him doing it and told him his penis would get sucked in! Poor guy.
I started when I was around 8 or 10 but I didn't really know what I was doing. All I knew was that it felt good, especially when I had the tub filled up and I played with the shower head. I think it started with cleaning and led to being curious.
I think I was probably 11-12. I don't completely remember. I do recall being aroused by particular thoughts and playing with myself as young as first grade. I think it's interesting that even then I was interested in BDSM type ideas even though I had NO idea what that even was back then.
I can't remember just how young I was, but I know it was most definitely under the age of 10. I don't know how I discovered my clit, but once I did I played with it almost every day. I do remember my sister catching me one time, and told me what I was doing was wrong, something I still struggle with to this day.
I think I was like 5. I was changing my clothes and brushed my finger up against my clit and realized how good it felt. I don't remember when I had my first orgasm, but I know I've had quite a few since then. ^^
