I had always played with my penis when I was a little, innocent, not realizing what I was doing, just random things like shaking it, squeezing, stretching, pulling, rubbing all kinds of lotions/creams into it, all sorts of things, then when I was younger I was getting more curious and more creative and bored with the same old thing, I didn't know about masturbating or orgasms or cum and it didn't feel great to play with myself, I just liked doing it, I decided to be more creative and had a great idea, I would put my penis in the hose of our vacuum and turn it on. I was small at the time between 4.5-6 inches and not thick at all. (Now I am 7.5-8.5 inches depending and thicker) so I easily fit my humble penis into the hose. My parents were out and I was home alone. I didn't know what would happen, but I was still very excited. I turned the vacuum on. Instantly I could feel the air around my penis lessen as it was sucked away. This felt strangely good.
I stood there for a while wondering why it felt sort of good, but it wasn't getting better, it was like a massage, since my penis wasn't fully developed yet, there was still some room in the hose it was in, gaps between my penis and the tube. I thought maybe I could rub it on the side, not like a stroke in and out of the hose, the suction made that difficult, but I began a humping motion with my hip/pelvic/thigh/groin area and I remember what I thought the motion was like when I did this because it is so rememberable, it was like something Elvis would do. This gave me what I thought to be a very strange feeling I had never felt before, but I kept going. In a few minutes, I felt pressure at the base of my penis and it worried me a bit, meanwhile the weird feeling was growing stronger, and began to overpower me. I felt something inside my penis and this scared me because it didn't feel like pee or anything, it didn't even feel liquid (though I now know it was) I actually felt it moving very slowly up the inside of my penis till it got to my head and held there. I did not know what to do. I was held at the edge of an orgasm and (I later figured out why the cum in my penis even though close to the opening wouldn't come out, I'll explain later) and then it happened, I climaxed and an hour or so later thinking back to that moment I realized how wonderful and amazing it felt. But when it hit me I freaked out. It had never happened before.
While I was still orgasming, (this all took a few seconds but slowed down in my mind) I shut off the vacuum immediately, pulled my throbbing, pulsating penis out, and saw the fluid coming out. It didn't look like semen which I knew about because of a short presentation I had that year in school towards the end about puberty and wet dreams and erections and ejaculating, but this wasn't like it had been described. It was white, but off white, pale and not thick at all, it was very watery, not sticky and looked like strange pee. I panicked; I thought I had gone too far, done too much, that the vacuum sucked this out of me and it wasn't supposed to come out or something. I thought I was in trouble and going to get sick or hurt and I rushed to the bathroom to examine myself. I seemed okay and a promised never to do that again. Half hour later I realized it must be semen though I wondered how that happened if I didn't have sex or have a wet dream? I calmed myself and thought how awesome it had been. I remembered from a library book that during sex the man moves his penis up and down. My dad had the sex talk with me but didn't tell me about the movement. That night, because I was horny, excited, and still worried, I decided to experiment to see if it was cum. I took an attachment for the vacuum hose and left it in my room. when I went to bed I brought it out and slid it over my penis, when I had a hard-on, I moved it up and down and found that my head was sensitive to it and continued for what seemed like forever, back then it took a while to cum, something like 20 min to 1.5 hours! But I cummed again and was relieved and felt great. This is how I would masturbate until I was a few years older.During this time I tried Vaseline with the attachment, tried other attachments, and when I couldn't use one, before I refined my technique to a stroke, I would rub the head of my penis with my palm till I came. This would usually take the longest. A little back in the story I told you I would tell you about a theory of mine:
I never did and still have not had a wet dream, so how did I know other than the vacuum I was sexually mature/maturing? I put all this together that day and figured it out, I didn't have dreams but I'd seen that semen-like stuff come out of me before, not with an orgasm, but random drops at random times, most of which were after a shower, or touching myself by playing like I described, usually with lotion and a tiny drop or two would come out and that used to scare me so much because I hadn't figured it out yet. This is why my cum that day was so watery and why it was held in my shaft right before the head waiting to come out, since I wasn't fully developed yet I needed more pressure and stimulation to orgasm. After that day with the vacuum, the droplets stopped for good. I'm straight and 19 years old and a college freshman. I still masturbate. I could go on with other stories but this was a long one. However, if anyone is interested let me know and I'll submit more.
