I'm almost fifty years old, and I've seen what's been taught in classrooms for almost as long. I've never seen "how tos" discussed in sex education, except for maybe "how to" properly use a condom or other birth control device.Leave the teachings of sexual perversion out of the classroom. Thank you.
You have a vivid and perverse imagination if you think that children are being taught how to have sex. I hope that it's not wishful thinking; if it is, you should seek out professional help immediately, before someone gets hurt and you end up, at the very least, with an attractive anklet that you can't remove.
