A major part of our system's attraction has to do with fictional characters, including ones we've made up and designed ourselves.
Due to a trauma history that includes corrective sexual abuse, we are very strongly attracted to men, while also being wired to find the same genders as ourselves attractive. This, and a few of the specific figures involved in our abuse, leads to us having preferences we feel are very specific and generally not fulfilled by people who exist outside the system.
Additionally, we are also attracted to some fictional characters due to their involvement in our abuse, or due to their similarity to us. Both of these things apply to Thomas Jerome Newton from The Man Who Fell to Earth, who is our main ficto partner (at least from media we didn't create); a large part of our abuse involved David Bowie media, which translates to attraction to the David Bowie character we find the most relatable.
If we want to experience attraction to somebody outside the system, we normally have to draw that person for ourselves. We therefore tend to rely on our own imagination or art skills when exploring our attractions - that is, a realm that most people would consider fictional.
Some of us also seem to find drawings more attractive than real people in general. This may be due to some trauma or similarly formative experirences that happened online and involved cartoon kink art. We consider this a form of fictosexuality.
Either way, we find it is much easier to turn to fiction - namely our own fiction - when looking for objects of attraction than to find people in the real world that we find attractive. While "aroace" isn't the full scope of our identity, as our attraction to men and the same genders as us is important to us, us being collectively ficto does account for why we may seem aroace to others.
