From a guy's perspective...I see male models and I wish I was in that kind of shape (and that young), but I wouldn't want to be that perfect.
As for female models, I dated one once and it was the worst relationship of my life. She was mostly pretty cool, but her friends (mostly models) were all pretty awful people.
The tall, skinny model type isn't my favorite female size/shape anyway and I know that's true for most guys. CURVES are where it's at! And everybody knows that any photo you see in an ad has been airbrushed/photoshoppe d within an inch of its life. Real women rule; fake perfection sucks.
