I don't mean the basics - the body, how to prevent pregnancy/ STDs etc. I mean sexual positions, innuendos, the things people enjoy doing together, slightly smutty observations etc.
Reason I ask is because we've had to speak to my niece recently about sharing too much sexual knowledge with our 10yo ds who keeps asking us what things mean and why she said it. Things like funny little smirks when the number 69 is mentioned and saying to him "do you know why I'm smiling?"
We're not prudish about discussing sex and bodily changes etc with our ds, we just don't believe a 12yo should be making these kinds of sexual references to her younger cousin. Dsis believes this talk is normal among that age group, particularly girls who will be going through puberty earlier than boys, although she doesn't necessarily like to hear it.
I can't remember what I spoke about at age 12 but I doubt I'd have known the Karma Sutra. Just curious really - is this a normal level of knowledge and banter? As a parent, how would you feel about your son or daughter talking like this?
