Came across the word cis today, which I looked up and discovered it means exactly the same to me as the word ‘straight’ always meant. So, has straight been run over by the politically incorrect bus and I can’t use that word any more?
Cis (aka cisgender) is the term for people biologically born as women, who identify as women or people born male, who identify as male. So, another way of putting would be: cis is a person whose gender identity matches the sex into which s/he was born.
