Trisexual

Trisexual is a term with multiple meanings.

Commonly, it is a joking term referring to someone who will "try anything" sex-wise. In this context it is sometimes spelled "trysexual". In this context, the term is seen by some as offensive, so should be avoided.

In a more serious sense, trisexual can refer to having sexual attraction to three genders, or can also refer to a person who fluctuates between being bisexual, polysexual, and pansexual.

Trisexual has also been used to mean sexual attraction to/sexual interest in trans people. This can be considered fetishizing, so should be avoided.

Flags
The original trisexual flag was created on or before 14 August 2015 by an unknown person. It has seven horizontal stripes of differing shades of blue, yellow, and pink. In this design, blue stands for attraction to men or masculinity, yellow stands for attraction to nonbinary people, and pink stands for attraction to women or femininity.

Another trisexual flag was designed by the Fandom wiki user WaterTwinkie on 15 December 2020. In WaterTwinkie's design, the pink stripe represents genders that are feminine in nature, blue represents genders that are masculine in nature, purple represents genders that are androgynous in nature, and white represents all genders.
