If the term transseuxal is inclusive of those who are not at odds with their physical birth sex, then I would suggest the word has been totally redefined, perhaps even scarily so.
My understanding of the term (and I have been active in the T* community for 20+ years) is that the need to change, or at least dsyphoria with one's physical birth sex is the defining characteristic of transsexual.
As such, while no-op transseuxal is quite possible (dysphoria with one's sex but not changing one's sex), one cannot assume all males who are women or females who are men are ipso facto transseuxals. Many, perhaps most, such transgendered individuals have no dysphoria with their physical sex and therefore should not be considered transseuxal.
Certainly, I am uncomfortable with having the term transsexual be expanded to include myself.
