I'm a hermit, and don't get out a lot, but I know TS's that are computer programmers, graphic designers, hardware engineers, authors, and contractors (Home improvement, etc.).
Hell, some of them are even cute. :)
One, a F2M, was at the birth of my son.
Remember the venue in which you ask the question. HA is, with no shame, a porn-centric forum. Many of the gurls who post here or who are yakked about here are in the sex industry to some extent. Yet they are not =ALL= of the TS's on the planet.
