Restrict the inquiry to heterosexual men in the United States. To be sure, famous rock stars have a lot of opportunities, but that is just one small corner of the distribution. Which variable is the best predictor for the population as a whole? Patrons of prostitutes do not count.
You might rush in and claim "income" or "status" and maybe those are the correct answers. But we're talking unconditional predictors here, and men with high income and status are a) often older, and b) often busy working. I'm not ready to sign off on those answers and anecdotally, when I think of the people I know, I don't quite see it. (It may be more true in Latin America, for instance, and that is one reason why visiting American tourists don't always succeed there. They first need to be certified by a local of high income or status, but instead they make some kind of foolish direct charge.)
"Facility with women" is too vague empirically and in some cases verges on the tautological. Maybe this is the most powerful variable but then I wish to re-ask the question and consider what variable predicts facility with women.
