More About Cis-man
The term cis-man is a complementary term to trans-man. Previously, the terminology allowed for referring to a "man" and a "trans-man." The implication being that one was the "normal" while the other represented a variation and thus something inherently lesser. The term cis-man allows for recognizing that there are multiple ways to be a man.
