NOob here, but having grown up in Las Vegas (actually working in and around the casinos) and now living in SoCal, so I might have a slightly jaded view...
The girls who are natural, and immaculately sculpted, for the most part, seem to seek appreciation for the hard work they've put in just as much as the sexual appeal of their figure.
The girls who go with medical science, and particularly the ones who go large, are doing it for the specific purpose of gain (financial, relationship, whatever) through sexual stimulation (initially). They know exactly what we want, and they aren't bashful about taking advantage of that. So, do we choose to let them?
In my case, absolutely! She has gone under the knife, possibly multiple times, in an effort to arouse and attract, so I make no apologies about sharing my appreciation. In a way, I see the plastic girl as a more risk free introduction, since the ground rules are already understood by both parties. I know her expectations and, if she has attracted me from across the room, it's likely we both know why and therefore, she knows mine. If later, you find out she has a brain and sparkling personality, the so much the better.
I absolutely love a girl who isn't ashamed, at all, about the testosterone puddles she creates. I would be on top of the world with our own Goddess Amy or a Danielle Derek on my arm. And not even because of the envy of every man (and most of the women) but because she would have the intended and obvious effect on my body and not bashful about using it.
my $.02 - now someone take this mic away from me and point me stage left.
