I've got three boars and one of them is a really quirky little guy (okay they all are, but if different ways).
I know most piggies don't really like having their back end/rump area touched and its pretty easy to tell if my other two boys are currently enjoying the contact or would rather it stops (they're up and down with it, they don't mind on the lap/like it but not so much in the cage).
Chester however goes all cat on me and lifts his butt up into the air and purrs (long purring) when I scratch his bottom and doesn't really do anything to get away (though if he's in the cage he'll walk away when I stop, but he doesn't run off and comes back in a few seconds). I'm not really sure if he's kinda rumble strutting me or enjoying it. He's a silly (but smart) little boy so I wouldn't put it past him (either option really).
