Kerry: Children yes children from the age of ten learn how to have sex through sex education...well I know my school taught us from the age of 10 (year 6).
As a parent you CAN teach your children what sex is...you DO NOT have to teach them how to do it ... humans have been breeding for how long????? How did the cave man learn how to mate??? Experimenting, watching animals, and seeing them birth newborn/eggs.
You can teach your child about 'how' to have sex when they are old enough (you think they are mature enough) by letting them watch the 'discovery channel'
When they start talking the birds and the bees talk, you explain to them, however you like, how you make babies. The rest is up to your child (hopefully when they reach of age) to make the decision when and how they will learn to have sex. All you have to do from that point on is teach them respect for both them and people around them and hopefully this will continue with a future relationship.
Of course this post is not aimed directly at you its to all those who think you learn how to have sex through watching porn
Porn only reinforces sexual characteristics that have been used by men from the very dark ages when they though women were less superior to them. This is not an image to prject to your daughter or son in my opinion.
