A sponsor pays to see you on a regular basis at a higher price and generally request you be available to only them. Think a child mistress. A benefactor, is a hell of a lot better. They do not require sexual services (although some do)...and just keep you like a child, pet, or something. The wealthier ones educate you and send you on trips around the world. Some even marry the children when they are grown enough. I have had both, but ultimately decided against both and chose someone outside of the system entirely.
