I'm a guy, myenzoorka is right. We would be VERY short. Masturbating gets rid of the that stuf, but its usually not a huge amount. Even if u ejaculate 20 times a day, it wouldn't hurt u. If u have any other questions feel free to message me.
um.... no.... masturbation or intercourse, those nutrients are set aside for that purpose and others go to your growth. if your worried, eat more calcium, protein, magnesium, ect.
No. If masturbation caused stunted growth, due to ejaculating the contents of semen, men would MUCH shorter than women. Then again, if masturbation did cause stunted growth, then most men should be about 50 feet tall - it could be an argument to masturbate more frequently (since being 50 feet tall wouldn't get you many dates.) Simply put - masturbation does not cause you to stop growing and the person who told you it does should have a swift refresher course in sex education!
