Do guys even notice eyebrows? I suppose if they were big, bushy, bresnev eyebrows that would be a bit off putting. But so long as they're within the range of what's normal, I don't think men give eyebrows a second thought.
My brain assigns them too small a value to make them worth including in my hotness calculations, probably e^-11 what I value breasts.
