Hey pal I saw in yout further remarks you have had EKG and Stress Tests. My question is, have you let your doctor know (in privacy) that it happens when your masturbating. That may be information he needs. Dont think he would tell your parents. I know it sounds odd, but I wonder if he would let you wear a heart monitor for a day or two, so he can record what happens when you are masturbating! Good luck!
The reason that you visited your doctor must be another one for the Guinness records book. What did he (or she) advise. Don't worry too much, as your heart rate increases, your hearts mitral valve goes out or sync with the aortic valve and prevents any arteries from rupturing. You also have a hand held pressure gauge !!! However. if it gets to the diameter of a marrow and reaches down to your knees, get your ass back to the doctor. LMAO.
Not trying to mock OP's issue but this thread needs this laugh. Don't worry about it I don't think you even need to tell the doctor when it happens just say you are concerned about your heart and maybe they can do tests. But at 16 chances are you heart is fine to jack it for hours.
According to the ancient Chinese wisdom grasshopper, a man in good health can ejaculate only once every three days. Also, it's much better to ejaculate less frequently during the winter. Heed this advice and you will prosper from it. What is "normal" or "usual" these days is not necessarily what is healthy. It's fairly common these days for young men to become porn addicts and impotent from jerking off too much.
yeah, and i didn't actually do 3-4 per day typically. there were those days but i think normal was about twice per day. but, this was before i had any real access to porn. i was using mtv, the travel channel, and my imagination. more importantly, has the pedophile been arrested or at least banned yet? i've noticed him harassing people all over the site, but this is the only time i've seen him come out and try to commit a felony.
