I have an 8 yo son who has been brought up in a very safe environmet, since he could walk he has kept his hand on his penis. My wife and I don't want him to think that he shouldn't touch himself so we just tell him that he has to be aware of it in public and we remind him, gently but still remind him. I think it's just a boy thing that we CSA victims, understandably, put a negative on. My touching of my penis was not as innocent but I have very different circumstances than my son.

I'm a freeman now, his authority's dead
no pain monger lies in my comfortable bed!
