When you masturbated the first time, did you know what you were doing?

no, my first ejaculation was a total surprise. It was seriously frightening! I didn't mean for it to happen and the feeling was so intense I nearly passed out. Email if you want to know the details. It was kinda weird to tell you truth.

I knew exactly what I was doing.

No. I knew that the stroking was nice, but had no clue what the cum was or that it was going to happen. I thought it must be a lubricant ...

I was 5 years old when I discovered masturbation and experienced my first orgasm.

I was in my bedroom after taking a bath. I had noticed that my penis would get really hard sometimes, but I didn't know why. This time, I decided to touch it. That felt really good, so I kept doing it. A few more seconds of this felt so good - I could hardly stand it. I stopped, but the feeling got even stronger, and a few seconds later, I had my first orgasm! It was extremely intense. I screamed and almost passed out! My whole body jerked so hard, I nearly fell out of my bed! I had no idea what had just happened to me, but I knew that I wanted to feel it again. I touched my penis some more. The feeling built up again, and I experienced my second orgasm just a few seconds later! Again, it was so intense that I nearly fell out of the bed! But....it felt so, so good! I was worried that I might not be able to get that feeling again. So...I did it again...and again...and again... I gave myself the 'special feeling' 10 times that day! I was very, very happy to discover that it wasn't a one-time deal, and that I could make it happen whenever I wished.
