In Rome and Greece, it is usually the old who teach the young, and they will form a lover relationship. The rich in the upper class are proud of having boyfriends. Many unearthed cultural relics have paintings depicting these. I remember that our library has a book, Life in Ancient Greece, and a chapter is devoted to this. The man will live with the young man, teach him to be a man, substitute him into the upper class, and become lovers with him. It's romantic.
