What's with the fuss about the use of pronoun here? He was perfectly aware that he was a male, he never desire to be a female. He's simply crossdressing, not transitioning. Thats why he was complaining why guys cant date other guy not why he isnt a female.
The problem here is he is demanding too much. Being a lover of someone is just the starting stage of being a partner in life with a prospect of marriage in mind. Although the west had a different definition, the rest of the world consider marriage as binding of a couple that want to start a family. For obvious reason, guys cant give birth, they can't start "their own family". So its perfectly normal why the dude reject him, it would be a different matter if he simply want to be friend and hang out with each other but nope, he want more than that, and the dude doesn't really think it would work.
