You’re at work, you get a call that your spouse or partner had been in a car accident. You rush to the hospital. It turns out that s/he’s survived and will be a full recovery, but there’s a catch. For some reason the accident has caused him/her to spontaneously change sex. Completely, right down to fully functioning reproductive organs. Nobody knows how to switch him/her back (short of a traditional surgical sex change). Basically s/he will live the rest of his/her life as a member of the opposite sex. Do you stay with him/her? Unless you’re bisexual s/he is no longer of your prefered gender. Could you adapt?
I am bisexual, and I still voted I’d leave. Not for me.
I’m straight and would leave her (well, him). Sex wouldn’t work and it’s an important part of long-term relationships to me.
Yes, that would indeed be the deal breaker of the week. But for others, I wonder if there were ever a case where both parties came to the realization that they wanted to change genders, did so, and stayed together.
Other. it’s possible that we might well stay together for companionship, yet turn to the outside for sexual gratification. As we have a semi open marraige now, it might not be that much of an adjustment to make.
Other. I’d no longer want to have sex with him, but I couldn’t just turn my back on someone I loved.
I see a lot of bowling in our future.
If my wife changed into a man, would she like women or men?
I wouldn’t want to have sex with my “wife” anymore in that situation but I bet she would make a great wingman. Assuming no other parts of our lives changed (like, for example, she suddenly didn’t like doing laundry anymore) I think we would get along well. Once she is male, my wife will understand why we need a mancave with a 60" HD TV dedicated only to porn. She would even help me build the bar and BBQ pit. Oh yes, I’m starting to get excited about this concept - what kind of accident causes this again?
That sounds kind of hot. I’d be into it.
Absolutely, if he stayed the same essential person. Same as I’d stay with him if he lost all function of his penis and stayed a man. Really, there are a LOT of fun, satisfying sexual things to do that don’t require a penis! 
(He’s got ED already, so this isn’t entirely new territory.)
Would I learn to appreciate his new vagina? Yes, although I expect I’d be a pretty horrible lover for a while until I learned how to bring him pleasure. I suppose it’d be about as skilled as a 13 year old virgin…which I was at one time. I learned how to pleasure men, I can learn how to pleasure women. For both our sakes, I’d be willing to learn.
Well at least she didn’t come to as a giant cockroach.
But as a sex partner another guy = giant cockroach. So it’s goodbye from me.
Well, I voted before reading the OP so I was thinking of some kind of purposeful sex reassignment, done on the sly. Which would be a dealbreaker.
If it was a freak accident – well it would probably still be a dealbreaker, although I’d be a lot more supportive. I wonder if he would let me date his sister, in that case?
I voted “don’t know”, which I realise is a bit of a cop-out, but I really don’t know. I love him to bits, he’s my best friend, and I can’t imagine life without him - but I have zero attraction to other women sexually, and I can’t imagine wanting to remain in a monogamous but non-sexual relationship.
If your SO unexpectedly changed gender you don’t really know them. Leave.
This person is my spouse and I love him (her?). He’s just been through a terribly traumatic event, no way I would just leave. I’m not particularly attracted to women, but I love that person. If he (she?) were willing, I would stay and try to make it work.
Honey, its not you, its me. I’m just not into guys. Sorry.
“Dammit Dr. where the Hell did they teach you medicine? Bow-Chicka-Wow-Wow-U…?”
This.
As much as I imagine I might still love my girlfriend just the same no matter what gender she was . . . I don’t think it’s true. I’ve never once felt compelled to be as emotionally intimate in relationships with men as I have with women, and I’m sure that over time I would loose the ability/interest in being in that sort of relationship with the man who is/was my girlfriend.
ETA: it’s not about sex, btw. I could see being in a committed, monogamous relationship with a woman with whom for some reason or other I could not have sex with.
What a ridiculous premise.
I’m straight, but only about 80% so - I’ve never had gay sex, but appreciate watching hot gay porn, at times. If my wife were still my wife, just with a dick, I might stay. I voted Not Sure.

She might be a close friend after something like that, but…“leave her” seems a bit harsh since I wouldn’t throw her out of my life (or even the house, really), but I guess it’s the proper choice when she’d be cut out of my sex life now that she was no longer my husband.
I would stay. At least give it a chance. I think I might peg a little closer to the bi quadrant of the sex-o-meter than I have explored, although my husband would not make the most attractive of women. But we’ve been together for over 20 great years, I expect that (s)he would still be attracted to me, as well as quite traumatized. If things did not work out over time, we would talk about what to do then.
If I were 30 instead of pushing 50 and had not been with him that long, I might have to give it more thought, but my first reaction on reading the OP was “why would I leave someone I both like and love that much at what is likely to be one of the most difficult times in his life?” I would probably adapt much faster and better to the situation than he would.
Stay with my new husband? Absolutely.
Most of the things that I love about my wife have nothing to do with her gender, and I’m flexible enough in my sexuality that I could probably get on board with her being a guy.
