Whenever I masturbate and that is at least once per week I feel all the build-up — but just when I am at the crescendo. When I'm about to ejaculate, it all dies away, nothing comes up, and this causes much frustration for me. It seems that I am holding semen in during ejaculation. Is that possible? Is it because of technique? Please, help me. I am 15 years old.
Well, it sounds like your problem is a little more involved than technique. Though you're still young and developing, it isn't normal for a sexually mature male to be able to get highly aroused but then be unable to ejaculate. One possibility is that your orgasms are just naturally very weak to the point where you barely notice them and you have a condition of retrograde ejaculation. In this case semen is ejaculated into the bladder rather than the urethra. That would be explanation of “holding semen during ejaculation”. Consult an urologist, if you're still unable to ejaculate in another year or so.
I masturbate since 11 and i still have sex now 5 times per week or even more if possible, still i also masturbate everyday like 2 times ... just do it, have fun!
I've done it when my foot rubs my penis on its back and just as its about to cum i'll have my heel on my cockhead not letting the semen come out until the ejuclating has stopped and then i'll rub it in my foot that's standing on my cockhead, it's great.
