At 17 it may be difficult to stop. I remember for me the desire for sex peaked around 18. I had to have it, was practically all I could think about.

If you feel wrong about self pleasure then maybe try limiting your opportunity for it. Get rid of any erotica magazine, DVD, and block x rated sites. Make a congnitive effort to avoid things that provoke you. Some medication have reduced sexual desire as a common side effect. Not sure if you are wanting to be that drastic.

Personally I don't find anything wrong with having a few knuckle babies if I have little bit of free time and the idea suites me. I mean your not hurting anyone. It is being done privately. (well it should, and if not that is something different). There are health benifiets to having an orgasm. A lot of people do it. No one really admits it, but I would say almost every adult has done it at least once.

Some people make it out to be dirty or shameful, but is it really any worse than sex?
