I find out my crush is trans and I am not attracted to him anymore
Why does him being trans mean you're not attracted to him?
I'm just not feeling attracted to him at all, he's actually unattractive now
You should try not to judge people solely based off of their gender identity. The only thing that has changed about this person is their identity, and the rest of them is still there. Try to understand their perspective and allow them the freedom to express how they feel.
I can't date a dude with a dixie stuck in her chest.
That is incredibly offensive. You shouldn't have these thoughts.
