Proquasexual is when one is exclusively attracted to feminine people or people with feminine presentation when one has a feminine gender or presentation. The attraction is based on the appearance of femininity and not necessarily gender.
The term was made for non-binary people who are uncomfortable with using terms like "gay" or "lesbian", though one may identify as gay as well as proquasexual if they wish.
Similar sexualities include: trixic, femaric, venusic, and lunaric. The masculine equivalent to proquasexual is proquusexual.
