Demiboy (also sometimes called demiman or demiguy) is a gender identity that describes someone who partially identifies as a boy or man, regardless of their assigned sex at birth. The prefix "demi-" indicates a partial or only partly felt connection.

Here's a breakdown of what that means:

Partial Identification with Boy/Man: A demiboy feels a connection to the male gender, but this connection isn't complete or fully encompassing of their gender identity.

One Part Boy/Man, Another Part Something Else: This partial identification with "boy" or "man" is often paired with another gender identity or a lack thereof. For example, a demiboy might feel partially male and partially another non-binary identity, or partially male and partially agender (feeling a connection to maleness alongside a lack of gender).

Varied Experiences: The specific experience of being a demiboy can vary greatly. The degree to which someone feels like a boy/man and what the "other part" of their identity is will be unique to the individual.

Under the Non-Binary Umbrella: Demiboy falls under the broader non-binary (or genderqueer) umbrella, as it describes a gender identity that is not exclusively man or woman.

Not Necessarily About Presentation: While a demiboy might have a masculine gender expression, this isn't a requirement. Their presentation is a separate aspect of their identity.

Examples of how someone might identify as a demiboy:

• Someone who feels a significant connection to being male but doesn't fully identify as a man.
• Someone who feels a fleeting or less intense connection to maleness alongside another more constant gender identity.
• Someone who feels a connection to the concept of being a boy or man but doesn't fully embody it in their sense of self.
• Someone who feels a connection to being male mixed with a feeling of being without gender (agender).

In simple terms, demiboy describes someone whose gender identity is partly male, with the other part of their identity being something else – another gender identity or a lack thereof. It signifies a nuanced and partial connection to the male gender.
