Cats are pritty complex socially, some being more inclined to be a dominant personality and others more submissive and have their own likes and dislikes just like people. Belly rubbing is a good example, some like it, some tolerate it and others hate it, just like people and nipple rubbing.
Male cats do have a tendency to aim for the dominant role, even over humans they will try and have you whipped. Our old cat would bite me on the nose if I tryed to sleep in and he hadn't been fed, if that failed he'd stick his bum on my face.
