This was a great post until you added those last two sentences. Condoms and safety? Seriously? When unmarried 15-year-olds (and these days many kids are having sex at 12 and 13) have sex with partners who "cannot be bothered", pregnancy is by no means the only thing that can cause them harm.

Casual sex is very emotionally destructive. These children are setting a low bar for future partners - no commitment, no thought for long-term consequences.

Good sex is about each member of the couple committing themselves to a lifetime of learning how to please their partner better - how to truly become united in every way. In contrast, when the uncommitted teen couple breaks up, at least one of them is going to feel as if they were objectified - used - for the passing pleasure of the other. That loss is something that can never be erased.

We should be teaching kids that this is a very important reason to refuse to have sex before marriage. Making babies who do not automatically have two loving parents is, of course, another, and there are many, many more.
