I refer this question to parents but i dont mind to hear younger opinions.
Kids start to masturbate at a very young age and naturally they are looking for something to arouse themselves. When i was 12 i was allready exposed to porn but i dont want my boy to watch porn at this age and get wrong ideas about sex.
If i got porn at the age of 12 before the internet era so i'm sure my boy can get. I would like to prevent that by offering him an alternative.

Any suggestions?
