[经济金融] How to talk to sons

Hi I'm Gina. % U7 q& x' {# s; o3 E' h

' Q; `' r$ `! p* x) F% @csuchen.deI have a question, maybe some of you can help me? $ X/ A2 E5 U! w% {$ f
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?
