My almost 7 year old DS has been showing a lot of interest in people kissing, being naked etc. he has been informed by a friend at school that sexing is when you get naked and kiss and rub your willy etc. he says he wants to sex with people as that's what his friend tells him they should do.
I have discussed things with him about what's appropriate and inappropriate and some ideas about how he can handle his friend saying these things. However I am unsure about when I should clarify the meaning of sex. What age would you do this and also any other tips that help me handle this situation?
