The point I'm making is that it seems the classification of mental disorder is thrown around with "alternative" sexualities depending on social acceptance. No acceptance? IT'S A DISORDER! Acceptance? It's perfectly natural!
Also, the law is not some infallible system of moral dictation. Morality as it is, is a fundamental fallacy due to the subjective nature of human consciousness.
Also, sex with those whom we now call "underage" has been common place in societies of times gone by, now we have age of consent laws that only prevent people from acknowledging that teenagers do, in fact, fuck, and that can only bring harm to those in question. Then you get situations like the hypothetical one proposed by the OP of this topic, ones like a 16 year old guy with a 15 year old girlfriend having sex being illegal (which, I'm sorry, is fucking ridiculous,) and so on.
If this forum is so full of rational, skeptical, logical people, then it is our duty to be skeptical of the law's validity and of the underlying moral compass dictating these laws. I don't see very much of that going on.
