I don't consider myslef particularly prudish, and always answer the DC's questions. So, for example, they know about childbirth, and a woman's anatomy ("three holes"!) etc.
However my eldest has never asked any more about how a baby is made etc and is still completely unaware of sex etc.
I can't decide whether to begin to introduce information about sex & relationships, or wait til he asks.
DH says he was actually quite scared/ overwhelmed by it all when he found out (bless!)so I don't want to rush into anything.
However I'm also aware that some of DS's friends seem to know more, and I will feel I've let him down if he's the last to find out, or has to find out from friends.
Any thoughts or experiences?
