I think "trap" is a subcategory of "femboy".
it's sort of like how all squares are rectangles, but not all rectangles are squares.
A femboy is one where you can tell it's a male, it's just a slimmer build. Often there's still a little bit of muscles shown.
A trap is what is colloquially known as "chick with dick".
A "twink" is what I would consider guys like LInk, Cloud, etc. They're slightly more effeminate than your typical guy, but they're very clearly men.
Then you also have shotas in the mix.
Basically, put the guy in a dress. If he looks exactly like a girl, it's a trap. if you can sort of tell it's a dude but you need to squint your eyes and look, it's probably just a femboy. If you can immediately tell it's a dude, it's probably a twink.
Of course, how the artist draws them can change things, for example Link is sometimes drawn extremely feminine. but I'm referring more to their official artworks, where Link is pretty much clearly drawn as a guy.
Of course that's just the physical aspect. The femboy/trap having a feminine personality and voice and mannerisms are also required to pass. They have to act and think like your typical (anime) female.
As for why I like them, I like traps more than "just" femboys. Since I consider traps to be "chicks with dicks", you basically get most of the upside of a girl, but swap out the vagina for a cock and balls, which in some cases is an upgrade. With a trap, you still have the mouth and butt for holes to penetrate, but you now have cock and balls to play with. Compared to normal girls, you mostly just miss out on big tits, which does matter, so I still love my anime waifus, but good traps are neck and neck with them and it depends on my mood at the time.
Femboys can work too, but usually the artist needs to give them more well-detailed genitals to compensate.
Traps are also in what I consider the "grey area" where they can be the bottom or the top, and thus can be in a lot of pairings.
