[Men] anyone else only interested in straight men?

I know when I see a straight guy. And the gay ones are always the ones I extremely dislike (mostly because they aren't my type and the way they act). I did get a gay kid msg me but he was ugly af sadly. "How do you know they are gay?" Really judging by how they talk, act, emotions, etc. (Really based on stereotypes but that's how most are my age).Does anyone else find it difficult understanding this? It's such a struggle!
