Just noting a few more things. First, method of BC (hormonal/IUDs) that are exclusively female and do NOT prevent STIs actually INCREASE STIs, in two ways. They are documented, heavily documented to reduce condom use in every study on the subject. There is also some idea, especially with Depo Provera, that the hormones alter the Yoni to make the entire region more susceptible to STI acquisition upon exposure. So the idea that all Sex Ed would prevent STIs is not exactly correct, because women could be encouraged to engage in behavior that actually increases the incidence.
I just read a little on Kinsey, who is the 'father' of modern 'comprehensive Sex Ed' and WOW! He was soooooo perverted and sick, and there is ample evidence he was seeking, in his 'research' to normalize his abnormal behavior. He was actually making porn in the attic of his family home, with his staff AND subjects, in the name of 'science'? I am on team 'throw out the totality of that man's research right now!' He makes anything Wakefield was ever accused of look like child's play!
Also I want to note that *I* was exposed to bestiality @ approximately age 8 through the famous 'My Secret Garden' by Nancy Friday, purchased by my mother, @ the mall. I didn't have her permission to read it, but that is what happens when you keep p*rnographic books in your family home & sell them @ regular book stores. I remember thinking to myself, 'that's it, there it goes, my innocence is totally gone'. I definitely felt maimed by reading that chapter.
