Cboy

Cboy, an abbreviation for Cuntboy, is a term used to describe male characters born with female genitals. This is not to be confused with transgenders or flat chested women.

Controversy over the term
There is some controversy over the use of "cuntboy". It's sometimes considered to be a derogatory and it's obviously not safe to say in an work environment because of how explicit the first word is; however, it's also the most memorable because of that exact word. Some people may use "intersex," a more broad term, to describe cboys but also others. The two terms are often used simultaneously on sites like e621.
