The TER description is fine as is, actually.  Trannies do have a pussy.  It's just located more in the rear than a genetic girl's, tighter and flanked by larger mounds of muscle.  If you are looking from her front, it's much more difficult to see not only because of its more rearward orientation, but also because trannies tend to have a much larger clitoris than a GG, which hides their pussy from a frontal view.  So look for her pussy from her backside.

Hope this helps.
