There is The Real World, and then there is The Porn World.

Shemales, ladyboys, trannies are mostly for porn use, unless you're really good friends with the Tgirl you're talking with, or unless someone asks you to refer to them that way.

Kinds of like how some folks call women bitches, cunts and sluts when writing free site descriptions. Not always the best way to refer to them in the real world.
