Utrinquegender is a gender modality that describes someone who experiences aspects of both trans and cis experiences. This is not due to being a closeted trans individual, but is a result of their identity. Examples of people who may identity as utrinquegender include:
- Female-aligned alters in DID/OSDD systems where the host body is AFAB, but has medically transitioned to male.
- Male-aligned alters in DID/OSDD systems where the host body is AMAB, but has medically transitioned to female.
- Individuals that have hormonal intersex variations that cause them to produce too much of the "wrong" sex hormone, causing them to develop secondary sex characteristics of the "wrong" sex.
Untriquegender is exclusive to alters in DID/OSDD systems and intersex individuals who have these situations.
History & Flag
Utrinquegender was coined by Tumblr user married-to-the-night on February 14, 2018. She coined the term as she is a feminine-aligned alter in a system, and the host's body is AFAB. However, other alters and the host are transmasculine and have a male-passing body. When she fronts she deals with dysphoria, presents femininely, and has to deal with fear regarding things such as how to refer to herself, which restroom to use, and what gender the body passes as. So despite being a woman in an AFAB body, she still experiences things similar to the experience of a trans woman.
The first utrinquegender flag was designed by beyond-mogai-pride-flags on February 21, 2018.
On August 23, 2022, married-to-the-night uploaded a flag they had designed. 
Utrinque means “both sides”, in line with cis (“on this side”) and trans (“across”).
