I do completely agree with this post, as an asexual person myself. I do, however, think we should also cut the writers a little bit of slack, as it is quite difficult to portray asexuality (even for asexuals) in my experience. Maybe we as a community just need to offer more feedback on what an asexual playthrough would look like. I say this because I personally haven’t seen many people offer feedback on this type of playthrough, even when it is an option.
I unfortunately can’t give any examples in the Choicescript format, but I can give an example from a Netflix show if that’s ok with you. Spoilers for BoJack Horseman by the way, I’ll spoiler tag them just in case. I think Todd from BoJack Horseman is one of the best examples of asexual representation I have seen to date. He really wants to have a romantic relationship with this girl he has a lot in common with, but they just aren’t compatible because she wants a more physical romance, while he does not. Later on he meets someone who he has nothing in common with, but is also asexual, dates her for a while, but they eventually break up. I think this is pretty true to my experience as an asexual person at least.
Essentially, the gist behind what I said in the spoiler tags is, if you’re going to make an asexual character, give them more in common with the MC than just being asexual. While this can be an important part of a relationship, it is also equally important that the characters actually like each other and have things in common beyong their asexuality.
Also, I don’t know if this is true for all asexual people, but at least in my experience, I get quite uncomfortable when it seems like the only way to progress in a romance is to do something physical. Some things are totally fine, like hand holding, as I do that with my friends, but when it seems like the only way to move forward in a relationship is to get physical with the RO, I’m not really a fan.
There are other ways to show your love and affection for someone beyond just physically. For example, an MC that might not otherwise show much affection, even to their closest friends and family, might repeatedly tell the RO that they love and care for them. This is something that the MC does only for the RO, something that is unique to their relationship together. Having things like this can make it feel like an actual relationship, while not requiring a player/MC to do anything they would be uncomfortable with.
Edit: I would also like to add, if your book does have sex scences, even in a “fade to black” way, please don’t make the only way to opt out of it be “I’m not ready for that yet” or “I think we should take this slow”. This can definitely be an option, but to have it be the only option makes me feel not great as an asexual person. This is because it makes it feel like the MC is either leading the RO on, promising something they might not ever want to actually do, or it makes it feel like the MC is going to have to do this later on at some point, regardless of how they feel about it.
I think most asexual people, myself included, would, at the beginning of a relationship let the other person know what their boundries are. So adding an option to the scene saying “I don’t think I want to do that, and I’m not sure if I’m ever going to want to do that” to opt out would be nice. This can also start a conversation about the MC’s sexuality with the RO, if it was not previously discussed.
