My definition of "playing with an ass": 1: Putting fingers, dildos, inside the ass, teasingly, or not so teasingly. 2: Teasing the butthole with the penis. 3: Any other foreplay method that is not actual continual, normal, rythmic penetration with the penis.
I'm so not into that. I also hate when a guy pulls out, looks at the gaping butt and then sticks it back in, muttering or saying something about the butt. Or when they pull out, tease, maybe spit at the hole and then put it back in. Or when they do a regular, pull out, tease, put back in and resume, followed by another pull out and repeat. Yeah, not so much. So, I didn't really say anything when he said that, since I was thinking in my head... "Oh man, he's one of those!".
