I was 12 years old when I had my first orgasm and ejaculation. I heard about jacking off but didn't really know what it was until I put together the pieces from things I'd heard from friends. I was laying down and I got hard and I started playing with it and stroking it and then I felt this amazing feeling building inside my groin and then I shot my first load. I knew that the stuff coming out was sperm, so it didn't surprise me. Suffice it to say, I've been hooked ever since!
I've heard from many guys who have said that they had dry orgasms before they could ejaculate and I envy them. I could have gotten in a few more early years of fun that way!
I had my first wet dream in my twenties actually, when I hadn't masturbated or had sex in a very long time. Wet dreams are pretty intense too!
