Well, it was part of my sex education, as well, and I attended a public high school. Certainly wouldn't hurt to show them. A dose of reality is what is called for when discussing the topic.
Yeah.....but I was 10 years at the time!
If it scared you enough to make you think about protecting yourself, then I would say, "Yes, it helpd." In my opinion, STDs are something every sexually active person should have a healthy fear of.
And unfortuantely we have some individuals that don't think it will happen to them.
