Asymmetry may be a very good indicator of developmental problems and lead the attractive to find attractive mates in some cases, but humans have other criteria they apply to potential mates, other measures of success or at least potential success. In some cases the urge to procreate overcomes the desire for high potential mates and the chosen mate ends up being whatever is left in the pool. Of course the natural tendency of human infidelity to chose better appearing candidates will modify this somewhat.
IMHO.
I guess what I'm saying is that the entire sexual selection mechanism is far more complex than is sometimes portrayed.
