Don’t attack me because I know that I am not the pretties person in the room but I don’t overvalue my attractiveness.

Anyway, It’s just a thing I’ve noticed while taking to some guys on tinder and badoo. I asked some of them how high they rate themselves in terms of appearance and all of them claimed to be 8-9/10 and in my opinion they were slightly above average looking (nothing wrong with that btw) so I was confused why they rate themselves so high. After that I got curious and I swiped right some unattractive men (obese, almost bald) to see how they rate themselves and yes, they said 8-9/10 as well. Do you think this is a common thing that men overvalue their sexual value?
