Essentially, Kevin is attracted to himself, narcissism 101.
This is most professed asexuals (and demiromantics) in my experience.
My personal theory is that a lot of the people now calling themselves "asexual" have removed anyone from their life who isn't a coom-brained degenerate, and have forgotten the experience of interacting with people who aren't coom-brained degenerates, so they unconsciously use "asexual" as a way to get the rapey people around them to stop hitting on them/harassing them/sending them gross porn 24/7.
Remember, the one thing these people don't question is identity labels, so saying "please stop sending me pictures of your disgusting butthole, I'm asexual" is a cheat code that might actually work, even if you were sending that same person pictures of your own butthole ten minutes ago.
I think there are people with broke brain/broke mind, or who never developed social skills and are coping. "Its not that I can't find someone to have sex with, I'm just Asexual".
The Asexual label really gets misused and applied - afaiac if you are jerking/flicking your bean to japanese cartoons, you have a sex drive and you aren't asexual. I don't care if its not even other humans, if you are stroking off watching videos of machines sewing leather cushions you aren't asexual.
A lot of "Asexual" people I've had the misfortune of encountering were either just some level of pornbrain or... I'm not sure what the term for "jailhouse gay, but instead of gay its japanese cartoons". And all that is stopping them from having a quote-unquote normal sexual drive would be someone willing to
have sex with them fuck that, just give them a handy and make out a bit.
(the female version is a little more tricky because they don't want to be seen as whores but same deal - if they could get some action from someone they didn't think was using them as slamwhale their status as ace would melt away)
I mean we saw how quickly Bonnie went from proud gay man with a flipped dick to burning down his life the second he got a taste of some obtainable BPD pussy.
But a lot of these people make this label a core part of their personal identity so even if things unfuck upstairs or downstairs, they can't just drop their asexual label and go through mental contortions to justify it.
There's tons of autists out there who will spend every waking minute gooning to gross porn, but call themselves asexual because whenever they meet an attractive person in real life, their crushing social anxiety instantly smothers any sexual interest they might have felt. You see this especially in the Superwholock types who openly lust after Tom Hiddleston but are terrified of real life men. They don't want to admit that they're just stuttering losers so they reach for the special snowflake label instead.
The other thing I've seen is people applying a bunch of other made-up labels is they hang around coom-obsessed degenerates and think those people are normal.
"Well, I am sexually aroused by other people but I'm not devoting 90% of my waking hours to some activity related to cooming; I must be asexual."
I had several friends who could not go more than 24 hours being single. They would hook up with the most toxic or troll-esque person they could find, or be cheating so they could drop their old partner and move in a (toxic, dysfunctional) relationship with the new person immediately, because not having a boyfriend/girlfriend was completely intolerable to their mental state. I like being a relationship but I'd rather be single than miserable, however if this self-label nonsense had been floating around and those people were my frame of reference I'd have assumed I was aromantic or w/e.
