Sex research is still in its infancy and not enough research has yet to establish firm categories for common human sexual behaviours. Though the rainbow flag already represents all different kinds of sexual orientations other groups however wish to identify with special flags for various political reasons- but I believe it is unnecessary and burdensome to fill up code-points with symbols which may only be temporarily in vogue, and which may hold no meaning in 30 years. The rainbow pride flag is more than sufficient to represent diverse sexualities which are a a definitely fixed construct. The colors reflect the diversity of the LGBT community, Other older uses of rainbow flags include a symbol of peace. The rainbow flag, commonly known as the gay pride flag or LGBT pride flag, is a symbol of lesbian, gay, bisexual and transgender (LGBT) pride and LGBT social movements.
