Maaturbation is good in limited amounts. when you get excited you relase that annoying liquid which lubricates the passage of the sperm. IN this process you also realease some sperms, if those sperms are left there then they become toxic, and lead to a lot of illnesses, including infertility. you need to whack off to get the toxic sperm outta your system, wet dreams aid this process but masturbation is more fun. also, if you don't masturbate or have sex atleat once a month your dick will shrivel up and your spem count will lower. its like a water well drying up if you don't use it. your body will weaken and your digestive system is also affected negatively with abstinence. biomedical science books will confirm this as well as a bunch of arab physicists have found this.
but excessive masturbation gives you a shit load of problems. you release too much serontin (sp). ecstacy users will know what this is. bunch of my friends used to take ecstacy and user to get alopecia, so i looked into it. when whacking off you get an overload of that same chemichal released, too much of it, leads to alopecias and other hair loss illnesses. too much whacking of also strains and shrinks the prostrate, which leads to cumming to early. its a psychological problem as much as a biological one.
do people wake up in the morning ever with back pains? peopple who have sex would get a sharper pain since the intensity of cumming is much stronger than whacking off. i dont know why that happens but it apparently weakens your spine and sinks your cheekbones (the sunken cheekbones is where the 'blind' scare story comes from)
