Waiting...

[VictoriaGotaSecret]

Do you think it would be fair to make my future spouse to wait to have sex until after I have a sex change?

[Desuetude]

That would be up to the both of you when the time comes. I don't think it's right to ask us seeing as you haven't met your future partner and making these decisions before even discussing it isn't the best idea. I think you shouldn't finalise anything, when the time comes you should both sit down and talk it over thinking about what's best for the both of you. You might find that upon meeting this person your views may change anyway so setting anything in stone wouldn't be the right way to go.

It's your body, and your decision. If you don't want to have sex, until you've had your sex change, then don't.
Like I said, it's your decision, not anybody else's.

[Twilly F. Sniper]

Honestly, yes. because it wont be the same after the change as it was beforehand. the private parts on one body would be different.

You have to wait until it actually happens, you can't just decide that without meeting said person. That requires a lot of thinking, and requires the other person to think about it. Until you're in said relationship, only then can you really decide. Like others have said, it's your body and you have the ultimate say in what happens, but it does take two people to go through that.
