Hello! Do you want ace representation? (You said aro but same difference, right?) We have
Asexuality 101: They're the token ace in The Sex Show and they say "I've never had sex before and I don't think I want to, am I... broken?" And then they learn about asexuality. Their entire character arc revolves around not having sex in The Sex Show. Completely unrelatable if you're anything other than sex-repulsed and alloromantic.
Asexual Book: it feels like reading a wikipedia article and will stop resonating once you're over the accepting-yourself-stage and start discovering yourself beyond the standard asexual experience.
Token Ace: they're the asexual character in the current big queer cartoon and she has significantly less screentime than the other characters. Confirmed asexual on social media.
Cartoon Animal: the creator didn't wanna think about them having sex because that's a cartoon animal. You'd be surprised how much porn people draw of this character.
The Dark And Mysterious Nerd: don't get your hopes up, he's also a tumblr sexyman and nothing in the source material indicates his asexuality.
Twink Of The Month: he currently has swarms of people going "asexuals can still have sex" but they're not really interested in exploring sexual relationships from an asexual perspective, they just don't want him to be asexual. The other half of the debate is working tirelessly to alienate sex-favorable people from the asexual community.
Ace Coded: they're the most asexual character of all time but it's not stated in the source material or confirmed by the author so you have to write a thesis in hopes that someone might consider that they could be asexual. You might get called homophobic if you do.
Alien Robot: their lack of interest in sex is directly tied to them not being human. The fanbase has a massive collective boner for them though.
Murderer: Yeah... Collective boner also applies here.
Actually Good Representation: she's from a piece of media that has a fandom smaller than the population of a small village and does not suit your taste whatsoever
Your Own Fucking OC: at this point, just do it yourself.
