Quick PSA, because there seems to be some severe lack of education regarding Asexuality among a certain bunch of opinionated people, who frankly have no place having such strong opinions about something they've demonstrated to be so ignorant about:
Asexuality =/= a lack of libido, sexual appetite, sexual drive, or sexual activity.
Asexuality does = little to no experience of sexual attraction.
There are many forms of attraction. For example, some of them may be: romantic attraction that you'd experience towards a romantic partner. Aesthetic attraction that you may experience when you see someone's fashion style or overall appearance. Platonic attraction that you may experience towards a close friend. Etc.
Asexuality IS a spectrum, we call it the Asexuality Umbrella; SOME people under the ace umbrella may experience no interest towards sex/intimacy whatsoever, some may experience disgust re anything sex/intimacy related, some may be indifferent or neutral about it, and some are positive or even enthusiastic about it. These things may include acts such as kissing and physical touch of the non sexual kind. ALL of these people are still asexual, and their sexual activity or lack thereof has nothing to do with it.
Asexual people may choose to engage or not in sexual activity, and the circumstances under which they choose to do so, and the reasons why, are very varied: physical pleasure, closeness to a partner, emotional connection, finding pleasure in pleasing a partner, etc, etc.
The ways in which an asexual person may choose to find their pleasure is also very varied. And yes, it may be through fiction, because it can be a safe way to do so without being expected to behave or perform in a certain way that may be uncomfortable for the individual. Nothing wrong with enjoying a good smutty book or fanfic, or comic. Harms no one involved. Enjoying this doesn't mean you're not asexual.
Asexuality does exist, and it's way more nuanced and varied than just equalling it to "not getting any."
Now read all that again, but switch Asexuality for Aromanticism. Also a spectrum, also varied, also incredibly nuanced.
So, yes. A fictional character CAN be asexual, AND also engage in sexy times with the chosen ship partner. A Queer Platonic Relationship is also a very valid option, because NEWSFLASH, sex is not the only valid bonding point of a relationship. It can be a strong, important one depending on each individual, but it's not the only way to connect with a partner.
And, NO. Asexual people are NOT "repressed." Asexual people do NOT need anyone to "change their minds". Asexuality is NOT a problem, a symptom, or a sign of trauma.
Some sources to know more about the topic:
AVEN - Asexuality Visibility and Education Network
The Invisible Orientation - by Julie Sondra Decker
The ABCs of LGBT - by Ash Hardell
ACE: What Asexuality reveals about Desire, Society, and the Meaning of Sex - by Angela Chen
There are many more sources out there, support groups and communities on social media that you can find mainly through AVEN, or with just a simple search about Asexuality on any search bar nowadays.
There's too much info about it now compared to some years ago to remain so ignorant about it.
