I've already discussed sex with my eldest son, because once he started asking questions, I knew it was the right time. I put it in a nice way, and there was no embarrassment on either side. Said, and forgotten about until he wants to know more. I think there's too much emphasis on sex these days, and children grow up fast because they're not given enough time to be the children that they are. Ours play. We interact with them and show a great deal of love and support. They're not out on the streets until 11 o'clock at night, with us not knowing their friends, or what they're getting up to, and they're growing up sensible and well adjusted. They have friends of both sexes, & when the time comes, they'll hopefully deal with sexual issues in the way that we've guided. This includes having respect for other people, and having been told about the emotions involved.
