Homosexual is attraction to the same gender; heterosexual is attraction to a different gender. The bi in bisexual is both of these, not attraction to two genders. Think of the bi flag, pink, purple, and blue: what do you think the colors represent? Nonbinary people have always been included in bisexual if you take some time to think about.
I have to remember to look out for myself because even though I’m trying to look out for a lot of people I care about, no one is looking out for me.
