Bisexual

 Bisexuality is the attraction to two genders, most commonly the male and female.

Flag meaning: The pink colour represents sexual attraction to the same gender. The blue represents sexual attraction to the opposite gender and the overlapping colour, purple, represents sexual attraction to both those genders.

Flag origin: The bisexual pride flag was designed by Michael Page in 1998 to give the bisexual community its symbol comparable to the gay pride flag of the larger LGBTQ+ Community. He aimed to increase the visibility of bisexuals, both among society as a whole and within the LGBTQ+ community.
