Once one is older and more experienced with women, one will be less picky.
I feel like it's those who are--for a lack of a better phrase--basement dwellers (virgins who masturbate mainly to adult video/hentai) build up very unrealistic standards to what is beauty and what isn't.
Even someone considered Goddess tier like Kirara Asuka will have her bad angles, her bad days, etc.
I don't think JAV stars have gotten uglier nor prettier. If anything, due to how much easier it is to appear in adult video be it major makers or one-man shops, the access to variety of body types has never been better. Truly something for everyone.
