Marginal Revolution: What's the best predictor of sex partners?

Marginal Revolution: What's the best predictor of sex partners?: "How about a portfolio approach. Friends of mine have been quite successful despite one being only 5' 7.5' but nice facial features, no athletic talent, very skinny, extremely bright, and a good talker. Another is 6' 2', college quarterback, nice facial features, nice guy, bright (not brilliant) but not super smooth. Both have obvious but very different attributes (other than reasonably attractive faces). I am kind of in between the two in most ways, and can't complain about my luck. Consider a hedonic model of the obvious attributes with a eye towards reproductive fitness. If your average is high enough and higher than her other options, you score."
