First of all, I don't think anyone (of age) really hasn't at least tried it. I imagine something like 99.9 percent of people (of age) do it on a regular basis, and the reason is clear: it's darn good for you! I feel bad for the religious types who claim it's immoral (cuz they do it anyway) and they must feel tremendous guilt and conflicting states of being. All heads of religious authority try to shame everyone into not doing it, but have you ever wondered why? Maybe as long as you're feeling guilty, you'll keep coming back (and they also get the added benefit of ensuring any attractive young women are primed and ready for being taken advantage of). As sick as the religious aversion to it is, that's how not sick and perfectly natural masturbation is.
