Besides personality traits (humbleness- sweet, kind, sincere, nerd), I tend to find tall men, a little on the tan side with dk. brown hair super-attractive when they have this certain look about them (kinda like Stephen Colbert).
Guys who are too muchismo turn me off. Guys who are a bit more medium built with a friendly smile get me most- especially when they're truly genuine, authentic, and really know who they are, are wise, mellow, appreciative, helpful to others.. attract me most.
Oh, and for some reason- when they either dress preppy or in gym shorts with white t-shirts. Metrosexual guys kinda turn me off. Yes, so simple, sweet, down-to-earth, modest, loves his family types of guys are eye-candy for me. Forgot to mention loyal (of course) & keeps promises. (I agree- it's rare I find a guy I'm really attracted to on all levels).
