i think, at the end of the day, the problem/reason is that courtship is still seen in terms of love rather than gender. whether that's a good thing or a bad thing can be debated, but that's the way it is as of right now. i don't think i would personally see that as sensible. and there's not really any operation to make a full love change at this point either, which is unfortunate, since it means that transloveual individuals are gonna have a hard time with themselves and with others considering they're kinda screwed on their biological love. hopefully one day that'll be different. but for now, it's going to be difficult for most people to find themselves attracted to someone whose love isn't snugly fit into whichever extremes they're attracted to. not everyone, of course, since there are people that do look at courtship in terms of gender, but that's certainly not the majority.
those are my thoughts at least
