I voted for 200+.
Seriously, though, about 140 pounds. I like a round, meaty buttock, significant thighs, and a decent rack. I don't like the stick figures, but I don't really care for the really big ones either, the ones that look like they just stepped out of a Paul Cezanne painting, or Picasso's nudes from his early years. Not that rotund, but I do like them on the fleshy side. And brunette. Black (or dark brown) on the carpet and drapes, with a dark complexion. In fact, to be honest, if they're dark enough, I don't mind the really big ones. But 140ish does it for me.
So enough cushion for the pushin right?
