I guess I've only seen this from the other side... 14yo girls whose mothers inform them they're going on the Pill now they have a boyf (my mother's friend, not my friend's mother in case you think someone made this up), mothers hiding sexual activity from fathers, mothers wanting to hear their girls are sleeping with the boyf...

I'll be talking to DS about abstaining (or at least not sleeping around) and the benefits there, I know he'll get all the mechanical knowledge way too early at school so I will need to put in the emotional knowledge. With girls... well, I don't want girls partly for this reason!
