It's probably more important to other people than it is to me. Like, if I woke up tomorrow and was magically turned into a woman, I'd still be very much in love with my wife, and I'd have pretty much the same opinions of everybody I know. But I know for certain that other people would start to treat me differently, both for being a woman generally and a lesbian (I guess?) specifically. On the plus side, it would be nice to have my whole name match my sex. My last name is a common female first name; lots of confusion in e-mails because of that.
