I've had conflicting reviews about my ass. Some call it big, while others tell me things like "you've got a cute little ass". I know my ass is definitely not PHAT, but I want to know what you guys would deem as qualifications for a big ass.

Background: I'm a small guy like 5'3" small, so it's likely that I won't ever accumulate as much ass as people with larger bodies. Therefore, in the grand scheme of things my ass isn't that large physically but proportionally I think it's pretty good. Like in pictures my ass looks nice because your boy has got a small waist, but when people get the luxury of seeing it in person they are reminded that I am indeed a small person so what they were envisioning/romanticising/objectifying may not be as large as they were expecting.

Anyways, I guess my overall question is: Do you guys consider a big ass as something in terms of proportion or actually volume?

Sidenote: I'm honestly not too self-conscious of my ass size. I'm just procr-ass-tinating.
