This is a complicated subject!
Attraction shouldn't be solely about looks but often is. Especially these days where social media has a lot to answer for. Why should someone who is considered pretty or good looking be vilified because they have the wrong shaped chin or nose?
I still can't work out (at 60+) why some great looking men have a plain female partner. Works the other way too, a gorgeous woman with an average guy. Perhaps the attraction is hidden (I'm not being crude here), a scintillating personality or kindness.
Attraction is mystifying
