Rate me autistic but I do believe that really ugly people have such low standards that they have no issues with finding another equally ugly person.
On the other hand people who look fair to middling tend have higher expectations in regard to their own looks and are more likely to turn down potential partners they don't perceive as attractive as themselves.
That results in having a trouble finding partners no matter how hard they try because people think that they're above the the ones who would gladly fuck them.
Edit: I agree with you
@Stowaway and have added some more words.
I'm tired af so excuse me if I'm not completely coherent.
