The primary self-destructive aspect, one which most non-psychologists seem to overlook, is the psychological damage. This is not to minimalize the other risks, but at least people are looking at them. Engaging in sex before the development of a stable sense of self is nearly always damaging to a child psyche. I have seen to many children who engaged in sex at a young age develop issues that needed therapy as a result ranging from relational issues and abusive partner selection to depression an in some cases swearing off sex altogether. Sometimes waiting years (post college or even into their 30s) before even beginning to reach out to establish an emotional connection on the level of a relationship with another person. The difficulty lies in knowing when is too early as there is no fixed age when this develops. Check any introduction to psychology or personality textbook for the relevant published research
