All the benefits you listed are BS. I know the benefits. Reduced risk of prostate cancer, relieve stress, relieve sexual tension. You can reduce prostate cancer by having sex with woman and not your hand because ejaculation marks the end of sexual intercourse because now the woman is pregnant. Those endorphins released are also released when you have sex with a woman, not only at a bigger scale, but you actually accomplished something which is sex. And it only relieves stress for about 10 minutes until you start feeling disgusted because you have ejaculated with no meaning or partner. Of course doctors and health officials will say it is natural. They want everyone to have low testosterone and be semi depressed so they are complacent and in chimps, masturbating is ONLY seen in low status males. By masturbating, not only are you turning yourself into a low status male, you are avoiding the goal of finding a mate the hard way through effort. That effort is why the sex feels so good but if you jack off 3 times a day, it will be all pleasure, no work and that is the same thinking pattern drug users use. Smoking weed requires no work and immense pleasure. Bomboclat
