I always just assume that I look gross to women. I'm usually right and just go on about my day.I see that look or the late "look away" from gal bikers all of the time. From a distance I look okay approaching, nice bike, dressed well, lean and not fat etc. When they get close enough to see my face and can see I am REALLY old and they do the "Ewwww, old guy". Makes me laugh.
