I have a question, maybe some of you can help me? - b1 B+ ^# |7 ]: S/ u
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? rs238848.rs.hosteurope.de9 E, I1 l3 i! \) p6 l5 v/ U
It really bothers me because i've found adult magazine in their room today.
3 k& w4 s2 ?" TShould I talk to them by miself or ask my brother to do it?
