It does not have to be a long drawn out birds and this is how babies are made and how to pleasure someone talk. Just a short and to the point conversation on birth control, condoms and such. I think if the lines of conversation are opened sooner these types on conversations are not as difficult. But if you keep silent until 16 and then try yeah its uncomfortable for both parties.
I wish my parents had been more frank with me. I got the learn from my mistakes talk (failed) from on side and I'll kick you out talk(failed) from the other.
I have already somewhat started this line of conversations with my sons. They are almost 8, 6 and 4. The 4 year old not so much. I had 2 cats spayed and neutered in the last year. My 8 yr old wanted to know a lot of details of why the cats had to have this done. And I was honest with them about it and call things by the correct terms. And since that time my oldest has asked a few more questions about those subjects. And yeah I was honest and told him what was appropriate for an 8 year old.
Sad but true kids are talking about this stuff sooner and sooner and I rather them get correct info from me than their friends at school. And no offense look at this board see whats posted that kids are to afraid to talk to their parents about. I would much rather have an open line of communication then get dropped a bomb shell at age 14-15-16 because they did not know anything.
