Neptunin

Neptunin, or otherwise known as nomascsexualgender, is an orientationgender in which one's neptunic identity heavily affects, correlates with, or influences their gender. One may feel that their attraction to non-masculine individuals has an impact on their gender that can only be explained by it. Neptunin individuals may identify as other genders along with neptunin.

One's gender can be influenced by one's neptunic identity in many ways. For example, one may feel that, even though they have a gender, they do feel fully connected to that gender, or feel as though their experience as an individual has been heavily influenced by being neptunic to the point that one's gender, and one's identity as neptunic become blurred.
