I like prefer a nicely shapened big butt. Don't gotta be EXXTRA THICC, but in the moderate where you can say"damnn that ass!" Though I don't mind EXXTRA THICC its just that some doesn't make the female seem to attractive.
I love a thick, round ass on my face, with a tight hole for me to tongue-fuck... but shape is more important than size, for example Sasha Grey has a gorgeous ass that isn’t too thick ^^
