A cisman, shorthand for "cissexual man" or "cisgender man," is non-transsexual man--a man whose assigned gender is male, and whose assigned male gender is more or less
consistent with his
personal sense of self. This distinguishes him from transmen, shorthand for "
transsexual men"
Gerhard, always felt like his cis man self,
knowing he was born into the correct body with which he himself
clearly identified - male.
