I have a question, maybe some of you can help me? 人在德国 社区. [' U' ^+ n, T1 K& J
At what age should a parent teach their son about ‘sex’ if there is no father around or would it be better for the kid to have a male family member to do this? ! i1 @, D4 ]4 |- u! N
It really bothers me because i've found adult magazine in their room today. 人在德国 社区8 ^; \. k2 P" K
Should I talk to them by miself or ask my brother to do it?
