Definition:
A person who identifies as a member of the opposite sex. Transsexuals usually desire physical alteration of their bodies to bring them closer to the sex in which they identify.

Pre-op transsexuals still have the genetalia of their birth sex, but live life as the opposite sex. Post-op transsexuals have undergone surgery to alter their genitalia.
