I’ll go along with all the guys (and many gals) here, thats its extremely important for a man to find his wife attractive.
Now consider this. Esther had a green complexion! Esther had been previously married (in fact she still was.. to Mordechai), and was “touched”. Esther was seventy five years old!
The Gemora (or Rashi) says that Hashem placed chein on her, which is what made her attractive- despite her age, despite her green completion, despite not being a besulah. I believe that the Gemora also says that if one is liked above, Hashem places that “chut shel chesed” upon them.
So as many said, a person can find a spouse/potential spouse very attractive , while the rest of world wont see what they see. It can be due to many things, most importantly, that Hashem makes them attractive to each other!
