Nofinsexual is the attraction to everyone except those who are feminine in nature (FIN) in their gender and/or gender presentation. The genders they are attracted to typically include men, masculine aligned non-binary people, neutral or abinary people, agender people, etc. They are typically not attracted to women and feminine-aligned non-binary people.
Some nofinsexual people might be attracted to women, so long as they present masculinely or androgynously. Similarly a nofinsexual person may or may not be attracted to men or non-binary people who present femininely. The exact limit of "feminine in nature" can be defined by the individual.
Nofinsexual was coined by an unknown person on or before October 5, 2015.
The nofinsexual flag was created by DeviantArt user Pride-Flags on October 5, 2015. Blue represents masculinity. Yellow represents neutrality. Green is a mix of blue and yellow. A lack of pink represents no femininity.
"Fin" stands for "feminine in nature", so the prefix nofin- stands for no feminine in nature.
