Leatherness, I'm glad that you chimed in on this thread (or maybe not; maybe it should just die).
So far it's pretty much been guys talking about their favorite female celebrities. Having been a guy for nearly 56 years, the circuitry isn't hard to track: beautiful face, beautiful body, and guy will follow.
It's women who are more inscrutable. There are guys like Paul Newman, Brad Pitt, Eric Roberts, and even Jack Nicholson in his early days whose female attraction most guys can understand.
But what about guys like Sean Penn? The guy's nose looks like it should be part of a fire hydrant. Plus, he's a major league...well, you know.
Guys pretty much want to look like guys they think are macho: Bogart, Lee Marvin, Steve McQueen, Sam Elliot, etc.
Over the years, I've heard my wife or her friends talk about this or that guy, and I ask myself, "what?"
Please, if you will, give your input.
