Think it was the year I was going to graduate, was 18 I think. Was in the bathroom after a shower and...eh..stroking off a bit then climaxed.

When I was 10, me and my sister were wrestling, somehow sje got her legs around my neck and her pussy was right in my face. After she let me go, I realized my dick was hard. It had never gotten hard before, so I tried to touch it, and well, that is how it happened for me.

I was also a young starter, at about six years old. It was before I knew what sex is, and, like NinStarRune, I just did it because the dry orgasms felt good. Also I wasn't yet fapping the way I eventually would fap; instead, I'd lie on my stomach, put my hand between mattress and genitals and kind of hump/move around. When I was 8 or 9, I'd start directing my thoughts to girls/women while doing it, and I was also taught about sex at that time. From then, a romantic scene in a film was enough to get me to go at it in private.

Happened when I was around 11 or 12. I think I was trying to go to sleep one night and I had a hard on for no particular reason. I started jerking off because that seemed like the most logical thing to do, and before long I felt this really weird rush over me, my entire body got really hot. I didn't know if I liked it or not, but I distinctly remember thinking to myself "Oh...was THAT an orgasm? That felt weird." Thankfully there wasn't a mess to clean up, and it would be a while before I would think to try again.

I was 12-13 and accidentally came across a pornsite on my flip phone and saw some naked chicks. I felt something in my groin then went to the bathroom and started fapping my lil dick till I felt something come out and felt relieved.

First time was when I wss 13, but when I started fapping it wasn't super amazing, just kinda stroked for a while because it felt good, I never actually came until a year later.

The first time i ever fapped was probably when i was around 10 or 11, i was watching some porn in bed with headphones on trying not to wake my younger sister who sleeping across the room from me and i was just watching this porno called what to do with all those amazing asses, anyways i was just fondling with my dick but nothing ever happened since i didn't really know what/how to cum, probably thought you could only cum by having sex. Skip a couple of years and i now had a computer and so during midday i would close the door to my room, turn the volume down to it's lowest and started looking at both porn and hentai now. This was when i then found the hentai game Legend of Krystal, and boy did i not expect what was about to happen. Couple minutes into the game and there was a bit where Krystal and the lizard girl where given a bj and i started to feel weird around the tip of my penis, so i slowly started to focus there until finally, i blew a powerful load which went all over my keyboard, monitor, desk and me. It was probably the reason i carried on jerking off to hentai.

I may have been like 11, 12, or 13 when I first did?
Pretty odd experience with playing sexual flash games and PornHub while masturbating. I didn't even have a proper erection nor ejaculation. Mostly precum. Would be like that till I got older around 15 or 16 when I was getting bigger and blow stronger, more thicker loads and having a good time doing so.

I was like 5 or 6 i think

Not a dumb question. No such thing. They call it Shlicking, but it's essentially masturbation with another name. As for my own story, I masturbated from a young age and into later years as well. Of course, since I didn't have the internet where I lived in my slowly approaching teen years, I was clueless as to what semen was, so I was a little freaked out when I saw it for the first time.

Shlicking can also be called Jilling off.

I don't recall hearing of that until now. And people say porn isn't educational! ^^

"Edubation"

the first for me was an out-of-body experience, no joke.
i don't think i ever orgasmed like that again. it was quite strange.

i was 13 at the time

Few things are like the first time.
