Interesting. We are very open minded with our children about sex. We don't pretend people don't do it, we dont shame them for being aware of their bodies. We want them to talk to us if they ever feel the need to. Of course we arent talking about the act of sex we just don't hide it from them if that makes any sense.My kids are in the full swing of pre-pubescent hormones. My 7yr old thinks girls are hot, while my soon to be 10 yr old has no interest in boys whatsoever.
We know another family who have been very explicit with their daughters.(6 &5) While I am all about knowing the proper terms for body parts these girls are exposed to a wide variety of adult sexual language that "I feel" is inappropriate at their age levels, however they aren't my kids so my opinion is just that. One day the 6 yr old wanted to see my son's *ding ding* as he calls it, he replied to her that is "potty talk". He did tell me what happened and I spoke with the parents who thought it was rather funny. I did not, but again not my kids..the point is that kids are going to be influenced by other kids and the values that the parents instill in them are what is going to make them curious about the opposite sex. I did ask my son what he thought about it, and he said he thought she was trying to get him into trouble.
On the other hand, I remember being around 10 or 11 and my cousin who is the same age having sex with boys who were 12 or 13ish and I was completely oblivious to what the heck she was talking about..neither of us were sexually abused ftw and we were together every single weekend from birth (our moms swapped weekends for babysitting) we were just completely different people and we still are today. IMO our differences stemmed from going to different schools and being around different peers.
