Weighing (ha!) in on the Hugh/Stephen physique discussion. I've always been really attracted to skeletally thin guys, so Hugh just looks lean and fit (and yummy) to me. My attraction to Stephen is much more enigmatic. It's intellect, kindness, sense of humor as well as physical looks that make me love me some Stephen.
When I don't have to sleep with them, I'm into skeletons, too, for some odd reason... the taller and slimmer, the better. When I lived in Germany, my landlord was this freakin' tower of 195 cm or so and had a waist you could encircle with two hands. That guy subsisted on a diet of 100 g of chocolate and latte macchiato a day. I swear I almost never saw him eat anything else. He also napped a lot. And then went out to dance the tango at night.
Reigning king and champion of sexy skeletons for me is an old classmate of mine from highschool. He was easily over two meters tall and I'll be damned if he weighed anything over seventy kilos. Also had really delicate bone structure - real bird bones - and was unbelievably pale. When our basketball team played against other schools, they chanted "Mr. Anorexia" at him. Semi-dressed, he was a rather creepy sight, but in tight jeans, a leather jacket and sunglasses? Rreow.
