I understand your question but it's not me who could answer it. I guess no matter how beautiful a woman is, (trans or not), a man has always a choice not to fuck her, even if he desires her. Would that make him gay? No.
I'm only a curious and anonymous visitor in the land of porn, so I can't post pics. Once on xpt the pics would probably haunt me (or hunt me?) for the rest of my life.
