So there's labels for romantic and sexual but platonic gets left out so much! Arretasexual is when you only get sexual attraction when the person gives you attention - this attraction can grow with more attention and fade with less attention and can even be all moved to another person if they give you more attention. It is considered to be under the asexual spectrum
I googled for a platonic version and got the "We couldn't find anything" screen.
So I made an unofficial flag (not as many stripes as the romantic and sexual versions, rushed, not much effort in it) for the platonic version
If you're up to it, feel free to improve the flag. This is just to give an idea for it.
So it's basically the same, you only get platonic attraction if they give you attention. I chose yellow because yellow is a friendship color to me and it seemed fitting because of that. Hope you like it, don't expect this to become a thing but hopefully someone who's been looking for something like this finds it ♥︎
