Nociswomasexual is the attraction to all genders, but A) one's attraction to women fades once it is known someone is a cisgender woman or B) one does not feel attraction to women until it is known that the woman in question is not cisgender. This term is typically used by transgender, non-binary, agender, or otherwise non-cis people. The term could theoretically be used by cis people however there is typically no reason for a cis person to do so as nociswomasexuality stems from a discomfort/unwillingness to have a relationship with a cis woman due to trauma, oppression, or other personal reasons.
The flag was recently changed (by Asphyn Falwell) due to the previous flag not fitting well with the sexuality.
The light pink triangle represents cis women. The dark pinkish-grey outline (around the triangle) represents the separation and disconnection between cis women to any other gender or sex identity. Finally, the greys represent the gender/sex spectrum.
