Absoulutly not! I'm 17 and have never done such a thing. It is barbaric, disgusting and unhealthy. It is bad for both physical and mental health. It is shunned in society, and rightfully so.
To answer each of your points, it is far from barbaric. People have been doing it for ages, without any negative effects on anybody else. If you think it's disgusting, wait until you see what actual sex is like. Trust me, real sex makes masturbation look like a playing with a basket of kittens.
As for the health factor there are no studies showing any detriment, mental or physical, do doing it. In fact doing it regularly actually decreases the risk for prostate cancer. Finally, it isn't shunned in society. Sure you don't talk about it too often, just how you don't mention your bowel movements in conversation, but it's assumed that just about everybody has tried it at least once, and that many work it into their normal routine.
OT, I do it about once a day before bed. It helps to relax me because I have some trouble sleeping.
