Celebrate Bisexuality Day
Celebrate Bisexuality Day has been official since 1999. To celebrate, go watch this fun 90s Blur video, support your friends who are out of the closet, educate yourself about the local community, go get a date and please avoid drunkenly making out with members of the same sex just because your significant other thinks it's hot. That's usually less celebratory and more exploitative, unless of course, you explain the situation to the third party in advance. (You can always ask for advice at Carnal Conundrums how to go about that politely.)
Let your Bi Flag fly as this part of our diverse community is celebrated around the world.
