Trisexual

Trisexual is a term with multiple meanings.

Most 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.
