Demisexual Pride Flag
Demisexuality is a sexual orientation in which a person feels sexually attracted to someone only after they've developed a close emotional bond with them. Forming a bond doesn't guarantee a person will feel a sexual attraction, but the bond is needed before sexual activity is even possible.
The black triangle symbolizes the wider asexual community, as black represents a lack of sexual attraction; the white stripe symbolizes sexuality; the purple stripe represents community; and the gray stripe represents the wider gray-asexual community, which demisexuality falls under.
