While it's hard to shift, as long as you're making an effort it's fine. If you slip up from time to time, especially early on, that's understandable. But eventually you should learn it. You were willing to call them by what they asked to be called originally, rather than just calling them "big guy" or whatever, so I don't think it's unreasonable to respect their wishes on what they wish to be called in the future too.

There is a big difference giving someone a nickname vs. assenting to a reorientation of outward identity.

Someone wants a nick-name? Sure. No problem.

Someone who was a guy/gal and now claims to be something else? Especially if he/she is actively known in a space as something before and _then_ changes? That's a HUGE demand that honestly shouldn't be something anyone is comfortable asking others to do.
