@kdfrawg sort of. From what I've heard and read from partners of trans people and from trans people I know who've had long term relationships and dated, and comparing it to what my experiences were 17 years ago coming out as "gay", it seems about as complicated, but the biggest difference between gay and trans dating experience partners and trans people dealing with a social role and potentially physical appearance changing if they're together around the time of making those changes. Which can be quite confronting, often people go through a grief process or aren't attracted to their partner anymore, sometimes it's horribly traumatic for one or the other person.
The other thing is that ability to be attracted to a trans or genderqueer person of whichever gender identity is probably itself a sexual orientation - eg there are people who are only attracted to cis women and trans men (this is not uncommon at all and many of those people might ID primarily as lesbians), or people who are only attracted to women cis or trans, or people who are only into androgynous people, etc etc. We don't really have words for this in our culture. Yet. And we don't have many dating apps that support being trans as an option, or meeting people who are into trans people (outside of trans fetishists I guess).
The issues for someone starting a new relationship "post" the big changes at least in my experience, in Australia as a university educated middle class person living in a town of 400k, more similar to what it's like to be gay- worrying if the other party has the capacity to be into you, worrying about disclosure, etc.
