No matter what, sex can kill you, but then again, a piano could fall on your head tomorrow. Life is a risk, not just sex. At my school, we had a 'Health Day' where they did separate us into boy and girl groups where we were taught everything in an open discussion, everything down to oil vs. water-based lube. I learned a lot, the various methods of testing used, etc. Now, of course, because it's a public school, the governemnt will fund abstinence programs which keep kids in the dark and increase the rate of teen pregnancies and turn the school into a pitri dish of STDs.
