My impression that "transgendered" as opposed to "transgender" is considered to be archaic and kind of a slur. I think because it implies that it's something done to that person rather than an intrinsic part of their identity?
In any case, I'd be on the same page as ChairmanSanchez and darthbearnc. I'd of course support them 100%, but let's be honest here, my orientation is sufficiently inflexible that I don't think I'd be able to remain sexual partners with them. I have nothing but respect for people who are able to do so, of course, and I'd certainly feel guilty at not being strong/flexible enough to make it work.
It was not precised that the partner in question would undergo surgery or modify their bodies in any way. As far as I know, there are plenty of transgender people who keep their body as it is.
