Ceterosexual, previously skoliosexual, is an orientation referring to someone who is exclusively attracted to non-binary, genderqueer, and/or transgender people
Similar attractions include neptunic/trixensexual (attraction to women and nonbinary people), uranic (attraction to men and nonbinary people), enbian (nonbinaries attracted to nonbinaries) and galaxsexual (a genderfluid person describing their attraction to nonbinary people). Lesbian and gay labels can also include nonbinary people in their attractions. There are more labels under nia/nin attractions.
Controversy
Skoliosexual
An alternate/outdated term for ceterosexual is skoliosexual, but the label was highly controversial due to "skolio-" translating to "crooked" or "bent", and thus ceterosexual was made as a replacement term. While ceterosexual is a new term, it uses the same flags that skoliosexual used.
Usage
Ever since its creation, ceterosexual has remained a controversial identity within the LGBTA+ community. Some claim that only non-binary/genderqueer people may call themselves ceterosexual, while others believe the term should not be used at all due to accusations of nonbinary fetishization.
On the contrary, many feel that this term should be available for anyone, because just as you cannot tell who is non-binary by looks alone, you also cannot tell who is a man or a woman by first glance either.
Etymology
The prefix cetero- means "other."
