The study you're talking about was actually Dutch, not Swedish. I seem to remember seeing something about it on the TV over here in the UK a couple of years back. Although the findings were just as you said, I seem to recall that the sample was pretty small - for obvious reasons - so they were reluctant to draw too many conclusions from it.
Having joined in on this thread now, I suppose I'd better do my best to answer your questions as well...
I guess if I considered myself anything it would be Androgynous. I seem to be stuck somewhere in the middle really - although I spend a good chunk of my time as a male I have a very strong female side that I need to express as well. Right now, I doubt I'd want to go any furthur than that but you can never tell in the future. I do find dressing sexy, but I've been dressing on and off now since I was about 12, so it kinda started before I began muddying the waters with a lot of sexual identity questions. However, if I am going to dress I like to look as feminine as possible. That would extend to meeting people dressed as well.
Being called Shemale or Ladyboy isn't great really - I've actually had somebody call me a Ladyboy once, just because I had long hair at the time (I wasn't even dressed when they said it either!) - and Tranny isn't wonderful either. Mind you, I've heard a lot worse - perhaps I'm just a bit too laid back about it
Sexually, I prefer cis women, unless I'm dressed in which case I tend to go for guys more, although that's not set in stone by any means. If I'm not dressed I really don't look at guys much at all.
