Some people think “I like relatable people and I cant relate to people under a certain age, what do you talk about” which simply means they tried the hot younger person first/eventually like everyone else and if they had any game or tolerance they would be with that younger sexier person
sexier by the definition of improved utility of sex henceforth making them more sexually attractive at all
