My son is turning seven years old and he sometimes touch his penis. We tried a lot to stop this behaviour but he still does that. 

Teach and talk to him the rights and wrongs And explain to him why it’s wrong

Just slowly educate him that it doesnt look nice and proper in public.

Talk to him la Make him understand and explain

LMAO that dude is savage bruh

Explain to him of his action

Talk and explain to him

Sounds normal.
