Gay Demiboy is an identity where someone is a demiboy and gay/vincian. This term falls under the non-binary gay umbrella. This term might also include gender identities that are masculine-aligned/male-aligned, including paraboys, libramasculine, etc. who identify as gay or vincian.
The first two gay demiboy flags are based on both the demiboy and vincian flags and were designed by tgoldie. The third flag was designed by Reddit user u/toxic-glitch on September 29, 2020.
