Dan, we are on equal footing here. What I was referring to is the practice of starting out an article with a short abstract, often three paragraphs long, summarizing the substance of the article. In the body of the article there are examples of those various forms that relations between men and youths can take, satisfying the requirements of the form. I agree, by the way, with your edit of the "prehistory" statement. I was basing it on historians' suppositions that Greek practices may have had a prehistoric precedent, but since that discussion is a bit tenuous it may best be left to the article on Greek pederasty.
