They give a flying **** about teenagers in high school being taught how to use condoms.
If you can't figure out how to use a condom without assistance you're clearly having more problems in your life than your education, lol. This is not rocket science nor beyond the ability of the average teenager to understand. Also, the companies that make condoms are so nice that they even put instructions in the box with pictures. I mean, you do know they do that right? (I've never seen a reputable brand of condom that doesn't include this information.)
Anyhoo, it's not the the old days and most pre-teens already have seen porn to some degree -- they know how the machinery works basically so the argument is invalid from both sides of the proposition. However, the biology is important to understand and material that they wouldn't run across through their and their friends meanderings.
