Have to disagree with you on that one. Why are there so many fat slobs walking around? That sure as hell isn't desirable. I have fat friends that are virgins because they can't attract the opposite sex (they want to attact women, but lack will power to diet and exercise).
Which I personally can't understand....I know once I broke up from my long term GF a few years ago, I lost 20 pounds of fat and gained 20 lbs of muscle because I knew I had to look above average again.
My current girlfriend....well I'm content to let the other guys slobber over her. I'd never cheat.
