I am fine with mutual masturbation and sucking off (69 is the next level for both of those, and I'm cool with it)...swallowing depends on the guy and his willingness to swallow mine. Only fair.
Ass play is kind of a next level I'm not sure about. I've had it done to me a bit and done it a bit...wasn't my thing.
Sounds like the OP's perfect situation would be a bi-MMF.
