How many time we can wank in a day .... and we stay healthy ?
Hi Man,
You can masturbate as often as you want but...
You can run out of semen in which case you'll have a dry orgasm.
You can train yourself to suffer from premature ejaculation.
To prevent the latter you should be trying to make your masturbation sessions last as long as possible - for HOURS. Masturbate until just before you orgasm, let the feeling subside, then bring yourself back to that point. Do it as often as you can. When you finally do ejaculate you'll have more volume and it'll feel better.
