In terms of face moreso than body.
Face wise we can have tons of debates. Some guys love classic Korean look, some like myself love that southeast Asian look, etc etc.
When it comes to being a "model", I feel like there's far less variance here. Generally toned, often voluptuous. I think low body fat is generally preferred in the world of Asians. But again, subjective. I do know short and chubby/fat generally is excluded from models... as is big boned/fat. Loose skin isn't very model-y.
As far as kgirls go, service and chemistry is almost all that matters to me personally, but sometimes there are girls who are hard to look at and they'd need a top tier service/attitude level to compensate.
I don't think looks get better for me even if w have tons of chemistry but I think what happens is that small things/nitpicks/imperfections can get ignored more as we develop chemistry and great sessions. For example, I never cared about busted teeth. Some folks might. It might be noticeable but after a gear session it's not relevant to me. Some mommy damage or loose skin can get annoying to eyes, but if the girl is great, you look past it.
I don't know. Then again I could never understand people who go for eye candy over service and chemistry. Like maybe if you're taking her out and showcasing to others maybe I get it, but like fucking a dead fish whom you have no chemistry with, is really drab. Maybe I'll get it 20-30 years later when I'm older lol. But for now, I think... being fun and having solid skills is all that matters to me.
Sorry badger, ended up a longer post than I wanted. Brevity hardly my forte haha.
