“If there is a boy who wouldn’t be able to think a brunets is beautiful then do all brunets a favor and don’t marry one.”
It’s impossible to know that you would NEVER find ANY brunette beautiful. Yes, everyone has their preferences, but sometimes that goes out the door when you meet someone and you realize how beautiful they truly are in your eyes even though it’s something you never thought you would appreciate. I have a “thing” for blue eyes, but I nevertheless had a serious relationship with a Sephardi. And every guy I ever dated until I met my husband was on the heavy side because I liked that look. My husband is average weight (and yes, he does have blue eyes, and incidentally he is also very into health and fitness, which I was missing out on with the others and really admire in him).
