This guest post from Arvan at SexGenderBody is part of a blog carnival to raise awareness and funding for Scarleteen.
In terms of group politics - there are large groups of people who are fighting to prevent you from learning any facts about sex. Facts that can effect your health, income, present, future, career, happiness, ability to have or enjoy sex, choice of sex partners and even the ability to have sex.
People get elected by using sex to scare voters - queer sex, teen sex, unmarried sex, kinky sex, fun sex, sex of any kind. Cultural practices and commonly held beliefs about sex punish or shame people for even discussing sex, much less teaching it to a classroom.
