So what if they do find out? It's hardly as if they're unaware of what masturbation's all about. Why is it that teens always seem to think that what they are doing is so wrong & shameful & terrified of their parents discovering their secret? Masturbation is a perfectly natural & healthy activity & normal in every respect. Even if they do say anything, just tell them that you are a sexually mature adult with according needs, and that how you choose to satisfy those needs is your own affair, and point out that it's better that you satisfy your needs that way than going out & getting someone pregnant, or picking up STDs. Mind you, the chances are that if they were to chance upon it they might be abit surprised, but they'd be more likely to diplomatically ignore it.
