I think there's an age thing here. I think older guys prefer curls! I'm telling you -- I get way more looks with curly hair than I ever did with straight hair. But this tends to be men of a certain age because, well, so am I.
(Except the other day, when I had a really good hair day, and I TOTALLY caught a younger guy looking. HA! Of course, maybe there was a younger woman behind me.... or I was dragging toilet paper off my shoe...)
Don't worry, ladies... the younger men will come around. They have a lot to learn about.... so many things!!!!
