There are a lot of things that you could say sex is "like", but putting a cat into a microwave oven is even beyond the "Max Mosley" end of the spectrum. The extract is from a "Christian" magazine of course, one of those Bible-belt literalist kinds where they neither understand their Biology or the social-science they're denying. Teaching teenagers that they should abstain from sex doesn't work, we should all know that by now (well most of us who were normal teenagers) pretty much every study that's ever been done shows that the most religious states in the US are exactly the ones with the highest rates of unplanned teenage pregnancies and STD's (Texas, Mississippi etc.). Biology and hormones trump Bibles every day of the week so if you're grown up about it and accept the fact that one day little Molly or Johnny is going to do what comes naturally, then the best thing you can do is EDUCATE them. If they understand how their bodies work, what to do and what NOT to do and can evaluate risks sensibly and have empathy for the feelings of other people then you will have nothing to worry about.
