They wouldn't, ofcourse. That's my point. If the parent is willing to take on the responsibility because their child isn't capable of handling the burden alone, then I think it should be ok. That is the alternative, to be sure, in a society that doesn't lock up the adult in question. I believe I have previously gotten into a discussion with Tiassa, wherein he mentioned the physical health risks of females below a certain age (15 perhaps) engaging in sexual intercourse. He stated that he wasn't completely sure about the validity of the study he had in mind, but I certainly believe that such studies are worth looking into. However, there is another point; not all sexual interactions involve sexual intercourse. Adult male engaging in a sexual activity with a young female or male present certain issues that aren't present with an adult female and a young male or female. The issue has to do with a certain body part of an adult male has that adult females don't have. Other than this, as to what should be considered ok, it really depends on the society in question.
