When I see a hot woman, I’m attracted to them, but also want to be them at the same time. Most of my fantasies are about becoming / being a complete woman, although after I climax, I literally feel like I want to just be a guy again and live my life.

Something that's only appealing when you're horny is by definition a fetish. This guy is textbook case of an AGP "transbian", and if he had more self more self awareness than a rock he wouldn't be so eager to prove our point about trannies.
