Sourcesexual is a sexuality exclusive to introjects in plural/median systems, whose sexual orientation does not align with their sources, yet they still feel a connection to their source's sexual orientation. Someone who is sourcesexual may feel as if they are/are supposed to have that orientation, despite not identifying/knowing they don't fully identify as such.
The coiner, TheNelsonSystem, initially made this term exclusive to traumagenic systems due to not knowing enough about other kinds of systems and fearing it may not accurately describe those system types, so while it was not initially intended to be exclusionist, it still was initially an exclusionist label against endogenic systems and was coined to only include traumagenic systems, but has since been reclaimed to include all systems, not just traumagenic ones. The coiner is not an exclusionist themselves and has since learned more about all kinds of systems and has learned from their mistake.
An alternate sourcesexual flag was designed by FANDOM user Unfunny person420 on April 10, 2021. The flag's color meanings are currently unknown, but it seems it's an edited of the primary flag but with equal sized stripes.
These flags may be controversial due to their exclusionary origins, however they may be reclaimed.
