I'll just list who my YES girls are but basically...anyone who has a fairly curvy, feminine body and is at least somewhat in shape:
Alana Laongcawk
Mistress Alicia
Gemini
Megan Snow
Amanda Coxx
Yandie Lee
Natalia La Porta
Lisa Stays Hard
Mia B
Peachez
Ms Dimond Dyack
Strawberrie
For NO list I won't say specific names, all I will say is that I personally am not a fan of girls that are super early in transition with super skinny/flat bodies, or on the flip side, girls are blatantly overweight (thick girls are fine but, I would prefer their stomach not be bigger than their ass). Again, these are just MY tastes, not meant to offend.
I've heard stories of models submitting "old" photos and then showing up to the shoot looking nowhere near as in shape as they were in their submission photos, so I know some of that stuff is beyond the control of the producers.
