Its not only mothers who worry,I would worry 10X more however if my son was a daughter Boys on the whole are ok,if they are a little street wise as my son is its fine,they have to be given some amount of freedom to find out who and what they are,to interact on the street with their friends,thats how they find their level amongst their peers,as for kids here having sex at 16 thats not as bad as it seems because we have sex-education at schools,birth control is readily accessible,I met a child in pinas 3 years ago,she was heavily pregnant at the age of 14 so its not only UK that has teenage mothers.
