General answer for most CDers: no, not all of us want to be women.
More specific answer that applies just to me: yes and no. I would like to be one, but only if someone could just zap me and BAM I'm a girl. :P You know, without pain and without surgery. Or wishing I had been just born that way. Wishing to be female does not equal a desire or intention to transition, and none of this necessitates any homosexual tendencies either. (Despite wishing to be a woman, I'm not gay. On the contrary, I'm strongly attracted to women...to the point that I kinda would rather just BE one.)
I'm curious: does your boyfriend visit these forums?
EDIT: The post above me, I agree with 100%!
