Is a 33 inch ass big And is it would it be a curvy ass for a 14 year old girl?

I am 14 and from a guy's perspective I have a nice ass but its 39 inches so you decide. But in a girls ass if you look at her from the side it should come out and kinda look like a bubble i guess and then compare it to a white girl ass which is flat so you should be able to tell if your ass is nice by yourself and if its flat there is no need to be ashamed you don't NEED an ass to get a guy you just have to work a little harder and hope you have boobs.
