@Fenrick: Oh boy, you don't even want to get me started.

I'll leave it to you to do the full research, but to keep it relatively short, purging your semen at least once every 2 weeks is what is considered healthy. Besides lowering risk of cancer and making sure your boy parts don't develop ED or Premature Ejaculation problems, males younger than 17 (but I use the age 19 for margin of error) cannot reabsorb semen/sperm like the bodies of older males. (Or in the very least, not as easily) So being pent up without release, especially for multiple months or even years like I had to endure in my youth, is really unhealthy, which is why males' bodies tend to nocturnally emit even more so during teen years than later in life; the body simply HAS to get rid of it in some way.

And that's not even touching on the psychological stress/damage being pent up too long can cause, especially in males with raging hormones and strong, uncontrollable urges during that age period too.
