I do. Clearly.

It was in a hotel room (fortunately my own room) while on holiday with my parents when I was 14. I was reading a novel that kept mentioning 'masturbation', and it went on to describe a scene where a woman was masturbating a guy younger than her, in a stock room at their place of work.
I immitated the described movements of her hand and soon found it was pleasurable ......... but didn't expect the outcum!
I spent quite a while cleaning up the mess I'd made so I'd not be shouted at by the cleaner.
Every chance that holiday I'd head off to the bathroom on the hotel floor I was on to wank off in the bath, the shower or the toilet.
It was extra arousing as there was an attractive single mother on the same floor as me and I'd often pass her as I hurried to the bathroom, sometimes imagining her wanking me off as the character in the novel did her younger guy.

Stong cumming sessions that week.

I did wonder later if that single mom knew what i was up to. I hope she did as she often smiled at me as we passed on another.

I don't remember my first orgasm as I was very young, but remember my first ejaculation well.

I was 11 and it was at night after dinner when I went to my room to "listen to music". I was in the habit of cumming three times a day, morning, after school, and at night after dinner or at bedtime. It was nice because all my orgasms were dry.

This time, when I came, I felt something wet. I looked down and there was a small amount of thick white liquid. I knew from porn what it was, and I had several older friends who had talked about their "wad".

I was so excited that I called a friend of mine who was older and told him that I could squirt now.

I was in the bathroom. I was very horny and my dick was rock hard. So I started to stroke up and down and it felt incredible. Much more intense than ever before. So I kept on pumping away and as I continued stroking my rock hard boner tingled like never before. When I passed the point ejaculatory inevitability it felt like waves of intense euphoria. It felt like the room was spinning, my body tingled all over and then several ropes of cum erupted from my dick and landed all over the rug.

I can remember my first orgasm. I had read something about fucking, sex and all that stuff so I used to grab my panis with my hand (lubed up with spit because the vagina would be wet in real life), lay on my stomach and did humping motions to play/simulate fucking.

At first I didn`t know how an orgasm would feel like. I only read, that it would feel very good. Well it felt good what I was doing. I did it several times without going over the top because I was a little scared as the feeling grew more intense.
Then once I was at it again and told myself that I`d keep going this time to see what would happen. So there I was fucking my hand, the feeling getting stronger and stronger until I had my first orgasm. As soon as I passed the point of no return I had to stop moving. I felt my penis contracting/pumping in my hand but nothing came out.

The procedure was the same the next few orgasms and then suddenly I started to ejaculate.

Are you serious?? That was over fifty years ago! LOL

I can still remember my first orgasm from masturbation so well even though it was many years ago. I was extremely late coming into the world of sexuality. My background and early years was extremely sports oriented and I was so focussed on my sport and studies that I never really bothered with anything like this until I was 17 or 18.
Of course I knew that when I read anything sexy or saw sexy scenes on telly or the cinema that my cock used get hard. Incredibly I never sussed out the pleasure it could give me until I bought a magazine called Forum which dealt with all sorts of sexual topics. I dont think it is around anymore but this was in the late 70s.
Well there was a chapter in this issue about masturbation and it outlined how men and woman could pleasure themselves. When I got myself alone in the room in the digs I was staying in I soon put the instructions into practice and began to rub and stroke my penis. It was fantastic to experience the getting hard and as I stroked more and more it was obvious that this pleasure was going to get out of control.
I was totally unprepared for what happened. I didnt realise there could be such pleasure. I just didnt know what was happening down there and at the point of no return my cock took on a life of its own and spurted the cum all over my chest and the shirt I was wearing was covered in this white liquid.
I was shocked but quickly got my composure back, cleaned up and promised myself that I would try it again better prepared!
Thus was the beginning of many many years of fantastic orgasms. Of course I love sex too and still do with my lovely wife but as her urge has diminished much more than mine I am so glad that I still have my trusty right hand to take me to the sweet heights whenever I feel my cock needs some attention.

I dont remember ny first dry orgasm. But the first time I came was in the bath when I was 10. I knew what it was because 12 year old boy had made a small group of us watch him and help him in a garden shed. We lloved it, I think there were four of us all tying to wank each other

This is an easy one to answer. I had a pillow with the picture below of Farrah Fawcett. I was a big Charlie's Angles fan. I humped the pillow until the inevitable happened. I still remember I thought I was going to pee. What a surprise when all that spunk came out.

Oh, yeah! I remember it vividly, even though I was only 5 at the time. My first two dry orgasms were the most wildly-intense & longest-lasting orgasms I have ever experienced.

I discovered masturbation & dry orgasms by accident just after my 5th birthday, while exploring my body after a bath. I had been getting erections for a year or more, but I didn't know what they were or why they happened. One time, things felt different down there. Sort of tingly. I decided to touch it. That felt really, really good, so I kept doing it. Within seconds, I felt all sorts of strange, but wonderfully-intense feelings building up inside of me. They got so strong that I couldn't handle the intensity, so I stopped touching myself.

But these strange new feelings kept building & building until I felt like I was going to explode. My cock started to pulse & jerk around all by itself, and then 'it' happened. And 'it' kept on happening for a long time! My body jerked uncontrollably as wave after wave of unbelievably-intense feelings swept over my entire body. The experience was so extremely intense that I nearly passed out.

I wasn't exactly scared, but I was extremely surprised and somewhat confused. I had no idea what had just happened to me, but I knew that I wanted to feel those wonderful feelings again. I was worried that it might be a one-time thing, so I started rubbing myself again right away. Sure enough, the strange new feelings started building up. This time I didn't stop. Seconds later, I experienced my second super-intense full-body dry orgasm. Again, my body arched & jerked so hard that I nearly fell out of bed, and the feeling was so intense that I nearly passed out. I was very happy to learn that it wasn't a one-time thing. I gave myself 'the special feeling' as I called it, 10 more times that day. I had never imagined that anything could feel so unbelievably good, much less that I could make myself feel such intense pleasure whenever I wished!

I soon discovered that if I kept going after the first 'special feeling', I could give myself as many 'special feelings' in a row as I could handle. I was truly multi-orgasmic back then, although I had no clue about such things at that age. I had no refractory period at all until I reached puberty, and I made the most of that at every opportunity. I was very happy kid! I spent a lot of time in my bedroom after that!

My dry orgasms were extremely powerful, full-body orgasms. They were far more intense and much longer-lasting than the ejaculatory orgasms I experienced after reaching puberty, and I always experienced 3 or 4 in a row, with only a few seconds in between. It often felt like one long 2-minute orgasm with a number of intense peaks, and I could just keep on going & repeat the entire experience over & over again until I could no longer handle the intensity.

At first, I thought that I was the only one who could get 'the special feeling'. I thought that I might lose my special ability if I told anyone about it. So I kept my little secret to myself. When I was 6, I learned that my best friend could 'get the feeling' too. We became j/o buds that day. We usually did it together at least a couple of times a day throughout our childhood & early teenage years.

I was 14 in my bedroom. Playing with it all at once I thought I had to pee and out came my white stuff. I had played a lot with an older teen so I knew what it was.. still I remember the first time he came like yesterday..

I was taking a bath and had a plastic bag full of warm water that I slid up and down over my 12 year old cock as I lay in the bath tub until it caused me to erupt with a great orgasm that felt so good that I was scared that I had just had a seizure of some sort, but after I recovered from my orgasm I figured that everything was alright and I used that bag until it broke (sigh)then I started humping my mattress and finally started using my hand. I still love doing it to this day.

I was about 13 and knew nothing. I had rubbed my cock with a soapy hand in the bath a few times and it felt pretty good, but I never had a cum. One night I was in bed just playing with it and it got hard. It felt good and I kept going. Suddenly my body started to spasm and I thought I was peeing the bed. I nearly passed out it hit so hard. I went to the bathroom and cleaned up as best I could, scared to death about what had happened. When I went to school the next day and told a friend what had happened, he told me that if I put that stuff in a girl, she would have a baby. My confusion was magnified. I experimented a few times until I learned what would happen, then I became more comfortable with it.

I remember my first ejaculation well, but I'm not sure how old I was. It happened accidentally and involved power tools. LOL. I was sanding the railings on our back porch one afternoon. Somehow the vibrating sander made contact with crotch (I was dressed at the time). I remember it felt good and I kept it there for a while. Before I knew it, I had an orgasm. Unfortunately, I was totally unprepared for it. I had no idea what had happened. Initially, I thought I had broken something and must be bleeding. I couldn't imagine anything else that could account for the warm liquid in my pants. That's why I think it's important for dads to have an early talk with their sons about what they can expect.

Very similar experience here; sitting at my desk doing schoolwork while absentmindedly playing with myself. Soon though the self play became more important than the schoolwork and I concentrated more on my boner than my papers. I'd done this before but this time was different and the pleasurable sensations just kept building and building so I kept playing and playing. Things just kept getting more intense until the inevitable orgasm and small ejaculation. I thought I'd broken something at first but figured out soon enough that that was what was supposed to happen! That was the first of the thousands that were to follow and, happily, that tally continues to grow!!
