Hopefully I'm not alone, but why is it so hard?

So, I've been wondering about this lately. I'm a 22 black gay man (I've attached a picture of me for visual help). All these things are important for what I am about to ask. But why is it so hard for me to find someone? I've been told that I'm attractive and most "claim" to be dumbfounded by the fact that I'm single. Most of the gay guys around me are in a relationship and they're white. Is it just easier for white gay men to be in a relationship than it is for black men? I would just like to know. Apparently, not everyone can give me a straight answer.
