People around the world have marked the tenth anniversary of the Celebrate Bisexuality Day, an annual event intended to demarginalise the bisexual community.

Launched by American bisexual rights activists Wendy Curry, Michael Page and Gigi Raven Wilbour, the campaign sought to draw the community out alongside the rest of the LGBT concepts after fears of its greater marginalisation.

One of the original activists said: “Ever since the Stonewall rebellion, the gay and lesbian community has grown in strength and visibility. The bisexual community also has grown in strength but in many ways we are still invisible.

“I too have been conditioned by society to automatically label a couple walking hand in hand as either straight or gay, depending upon the perceived gender of each person.”

Events in aid of Celebrate Bisexuality Day have taken place in America, Canada, Australia and the United Kingdom displaying the Bi Pride flag designed by Page.
