No matter who you pick, any relationship you’re in would be at least a little bit gay. Alternatively, you can test hypothetical relationships for gayness using this model.

Being aroace makes it a lot easier - if you’re never in a relationship, you are therefore never in a straight relationship, and therefore you are always gay. QED and all that.

Being gay is liking the same gender that you are, so liking other enbies would be gay in your case, I suppose.
