Like, seriously, I have had a few people talk about how my fiancé wasn’t conventionally attractive, but he’s attractive to me :)
Plus, he’s good to me, and I don’t date for looks. I’ve had conventionally attractive exes too who have been horrible people, so…
Many people are themselves not particularly attractive, so this is may be a matter of realistic expectations.
It’s only interesting when there’s a large disparity in attractiveness which is generally anomalous. I think “many” falling into this category is probably an overstatement.
