It only makes sense that it has a variety of benefits.
Imagine being a caveman. What's one thing that you'll probably do every day? Masturbate, of course. If it caused problems, your dick would fall off.
(or something; that just sounds funny)
But, if it helps, then you'll be healthier, and you'll be more likely to reproduce, probably many times over. Then -- guess what -- your offspring will also inherit whatever characteristics that make for healthy masturbation.
This is Darwinism at work.
