Hey if my son is 11 years old start to play with his safe at a young age is it a good or a bad thing and will his health be good?

I would say it is unexpected at his age and likely reflects exposure to self-pleasure by an outside source. It could be from another his age or older. Exploitation does occur at this age. The event itself doesn't harm anything. Your reaction would be to encourage him to keep it private. Shaming him can be a long term neg Making sure he has other productive activities to spend time on is important.
