Mens libidos dont always follow perfect 10s. We know Arnold Schwarzenegger didnt. Men will sleep with all kinds of women.
I was swooning over Elizabeth Hurley for years when, at the height of their mutual careers as Hollywood heartthrobs, Hugh Grant cheated on her with a streetwalker that looked somewhat like Michelle Obama after a few years of drug addiction. I was appalled and confused. I simply do not understand some guys...
except, of course, the times when I was tempted by some woman at some moment, even though my significant other was far more attractive, inside and out. Proximity and unfamiliarity are mighty tricky temptors sometimes.
