We had sex education lessons in school. I've no angst with age appropriate lessons about bodies, puberty, reproduction, consent, saying no - but I don't believe children need to learn about anal sex in school lessons.
We'd pull ours out of such lessons until their ages were appropriate. Parents can teach this themselves, they've lived it.
Musing over your comment, the thought occurred to me - what's the bloody hurry...
At age nine, a child has it's whole life ahead. A whole life to build relationships whether they be long-lasting or not, to 'experiment' (or not as the case may be), to learn and understand the nature of not only their own sexuality but that of others. I just feel it should be taken more slowly - a child should be allowed to absorb each step in the journey without having to rush into the next one. So to speak.
It's as if we have to cram their heads with as much knowledge as possible in the shortest time possible. And, again, this leads me back to the belief that sex education is being driven by our now overtly sexual culture - and pornography. Indirectly, of course. In order to protect them from what they might see at the press of a key on their smart phones, or what information and graphic illustrations that might appear on their screens sent by their more worldly school mates, we have to 'force-feed' them with information that they might not really be quite mature enough to appreciate or even understand. Some nine year olds - and older - are still at the stage where they think the opposite sex is a 'bore' or a PITA. I know of one child neighbour (nine or ten not sure) who, when asked if she had a 'boyfriend' rolled her eyes in exasperation and told us that 'boys' were just so "stupid". I don't think she's quite ready to absorb the area of anal or oral sex just yet. She's very much into her hobbies of horse-riding, puppy-rearing and ballet.
If she were my daughter, I'd want there to be a little pause in her sex education if it included such information. There should be no great rush. Plenty of time in the next couple of years to get to grips with it. No?
