Steve, excellent examples!!
While I am not lesbian (haha), I do admire other womens' physiques constantly, and since they are beautiful creatures, I will contribute my opinion.
I think that if I were a guy, I would definitely be more for the curvy girls, or "voluptuous" as Steve calls it. Coming in close second would be athletic girls, but just not too lean. I used to be into the super lean look, but lately (even for my own physique) I've been preferring a softer and more feminine look.
Not to say they shouldn't work out, but just as far as bf% goes
