I think something like this is mostly just left up to the mind of the person you're roleplaying with and their in-character idea of 'is the person pretty or not because I think they are.'
You can roleplay your character with a description, mentality that defines them as your personal ideal of handsome to a point where they have the attitude that matches them knowing something like that but to the next person you might aswell be some mediocre peasant while to another you're an arabian prince riding a white steed that attracts women like a brand new lamborgini.
