What makes Arthur so attractive?

I genuinely haven't seen or heared one person who thinks Arthur is unattractive. I've started playing RDR2 because a friend of mine (straight guy 😭) constantly said he would "buss it down" for him and I wanted to see what the hype was all abt.

So I'm wondering, what exactly makes him so attractive? Or are there features that make him unattractive?
