All this talk of spinners, BBW, rubenesque, curvy, etc women is getting me aroused. ;) Personnally, I find all (well almost all) women to be beautiful. Age, size, shape aren't realy that important. All women have great features (legs, breasts, eyes, hair, personality, smile, skin, laugh...) and it is their unique combination and uniqueness that is so appealing.
I think it is important to be honest with your pictures and descriptions so as not to mislead anyone. If I am in the mood for a particular "type" that day, I don't want to be surprised by a different type when she opens the door, even though she may be exactly what I want on another day.
