It's hard to say what he is thinking and the only way to find out is to talk it over with him. I've never had this type of relationship, but if I ever did, it would have to be with a kind and considerate partner. Not one that would treat me like a piece of meat to be enjoyed purely on his whims.

If he had done anything less than what you posted I wouldn't consider him a friend, let alone give him any further benefits.
