Thanks for writing to health care magic.
I can understand the problem you are facing.
You should discuss with your kid. There is nothing wrong with that.
You should also explain to him what is right and what is wrong.
You should also educate him regarding the hazards of unprotected intercourse
If you are facing problem with discussing all those with your kid then you should take the help of a doctor to explain the same to your kid.
Hope this helps.
