Well we are playing a D&D game, 5/8 races have bat ears.
True enough, and D&D has even more races, some that don't have ears or who are furry or made of stone or whatever. I doubt that I would be eager to romance them, either!
It is one of the oddities of so many sentient humanoid races - players (and developers) seem to want to have them appeal to human (player) mind. Hence most of the standard races basically resemble humans with extra bits stuck on. Even representations of the Githyanki are becoming more humanised (compare the 'modern' versions to the creature on the old Fiend Folio). Monstrous and alien is becoming familiar, sympathetic and more human-like.
Anyhow, I'm not one who has ever really found D&D's elves attractive. They are elves, a different species, not just slim humans.
