Finally, there's this consideration. I'm sorta scared of men when it comes to sexuality. To everybody suggesting this in the comments, yes this is probably somewhat sexist, because it's due to fear, not sexual orientation in my case. But my fear is stronger when it comes to black men. So yes, that's racist. There's an explanation here, an attempted sexual assault when I was 10, and the total absence of any black men in my surroundings/social groups, be it before that event or after it.
