I've had at least two weeks worth of sex ed lessons, every year since year 6 (I'm moving into year 12 next year) and they're STILL telling us "The penis enters the vagina. The sperm connects with the ovum." They've taught us how to put a condom on, about STIs, contraception, periods, puberty, birth (oh, way WAY too much detail on birth. If I have a baby, I'll go to some of the birthing classes thank you very much) and pregnancy and pretty much everything else, which is better than some schools. But there's still a lot of people in my year group who get up to everything with everyone, without protection. I think the problem is that my school said nothing about relationships - eg, "before you have sex, know what you're doing, do you respect and trust this person? Do you feel you're really ready?" Not just, "Hey kids, have some free condoms!"
