How do you define your intimacy in an asexual relationship?
To be honest, I think your best bet would be to research love languages (sorry if this has already been suggested!) There’s five types: verbal (compliments), gifts, spending time together, physical touch, and acts of service (cooking dinner, cleaning house, fixing cars, etc)
If it’s for a character who you are developing as the writer, consider which of the five they would be drawn to most. If it’s for a player defined character, consider creating a variable of some kind (love_language 1-5) and using multireplace perhaps to list the various options of how they interact with their partner, what they fantasize about doing with a crush, etc.
Also, I feel like it’s important to note, some ace people still engage in more sexual contact with a partner depending on how sex-repulsed they are. Some folks are sex-repulsed, which means they feel adverse to sexual contact and/or content in media. Some are sex-neutral, which means they don’t really care either way. And some are sex-positive, which means they still enjoy reading smutty fiction, would have an enjoyable experience if their partner wanted to have sex, etc. Being ace isn’t a hard limit to all sexual contact, it just means that any sexual interaction has “caveats” so to speak, such as their motives for engaging with it. Just make sure if you’re not an ace person and you write someone ace who engages with sexual themes, you try to get someone ace to give it a read over.
What attracts you to other people the most?
I still have a romantic orientation, which I define as biromantic (i.e. all folks, though I tend to avoid cis men; nothing wrong with them, just not my type.) For me specifically, I have different tastes depending on the type of person I’m attracted to; I find girls who have dark hair or very light hair to be especially beautiful. Physical attraction is still a factor, I believe, but think of it more like if you’re thinking about buying a piece of art, you want it to be something you like looking at, even if you also like the history and themes of the piece. (Not to equate ownership with relationships! I mean more the “commitment” aspect of making a purchase.) I do think however that without sex being a factor, personality takes a really big spotlight. When I think about a partner, I want someone who meshes well with my own personality, and who I can enjoy spending time with and talking to.
How would you want asexuality to be represented in a game?
I would want asexuality to be represented in a mature, and positive way. All too often I see people say that ace folk aren’t discriminated against, aren’t really LGBT, etc. Further, a lot of times ace characters are watered down to a trope of super innocent, naive, childish, etc and are almost exclusively sex-repulsed (“sex is icky!! cooties!! ahh!!”) Just like any other LGBT character, your ace character may or may not be a virgin, may or may not have experimented with sexuality for who they have dated, may have any personality you can think of, may have “adult” goals, etc. Try to avoid making a character being ace be their entire identity.
