We had a thread on that topic once before, and IIRC that one also went a bit peculiar. I guess it's a sensitive subject. Anyway, I had posted in that thread about a friend who feels that her lesbianism is a hangover from her past life as a heterosexual man. She'd undergone a hypnotic regression and recalled abandoning his/her wife while the wife was ill and dying. My friend feels that it's part of her karma to live out the female role this time. Not exactly a matter of being in the wrong body, but kinda-sorta nearing the same ballpark.
