Viramoric is a diamoric orientation that refers to non-binary people who are attracted exclusively to men. The term is necessary because most other ways to say that one is attracted to men involve the assumption of one's gender. For example a straight person attracted to men is a woman, or woman-aligned. A gay person attracted to men is a man or man-aligned. Some non-binary people are uncomfortable with this, so the term viramoric was created to state attraction to men unrelated to one's gender.
The feminine counterpart to viramoric is feminamoric.
Another term to refer to this is androsexual, though some people are uncomfortable identifying with this term as it can be considered transphobic, because the prefix andro- literally translates to penis.
