A very big YES to that question. There is nothing worse then some poor child being victimized due to ignorance about sex and it's repercussions and while I started talking to my daughter at an early age, the classes that she took gave her some information that was current and very necessary for her to know for her own well being as well as anyone she was going to be intimate with.
I took a few classes about 15 years ago as an adult re-education course for women getting back into the work force and one of the classes as a sex education class and while it focused on educating women on what constituted sexual harassment it also touched on some basic facts about STDs. Half of them I had never heard of much less knew the warning signs or symptoms of and I was a divorced mother of two.
In my opinion, having young people learn about sex in school leading to them actually going out and having sex is stupid and shows a lack of understanding of what is actually taught in the classes. If my daughter is an example of most young ladies, her opinion that sex these days can be scary as hell and should NOT be ventured into lightly and without all the facts, is probably the norm and not the exception.
Sex, while pleasurable, is not worth dieing for and if one person learns that from a sex education class then it's well worth it no matter how uncomfortable it makes some people.
