"My favorite definition for bisexuality so far is the one popularized by (the wonderful) bisexual activist Robyn Ochs. Ochs says, “I call myself bisexual because I acknowledge that I have in myself the potential to be attracted—romantically and/or sexually—to people of more than one sex, and/or gender, not necessarily at the same time, not necessarily in the same way, and not necessarily to the same degree.”
This is by far the broadest and most enabling definition of bisexuality that I’ve found to date. Its strength is in the way it enables anyone who wants to identify as bisexual to do so. (In other words, it reassures people.)
In a world in which bisexuality is usually very narrowly defined, many people who experience bisexual desire, and want to identify as bi, often feel afraid to start (or keep) identifying as such, as they feel as though they “don’t qualify.” The role that an enabling definition for bisexuality can fulfill to counter these feelings of internalized biphobia is invaluable—and I feel that Ochs’s definition does just that. It reassures people that they are “allowed” to identify as bisexual if they wish to do so."

The part that is above the water is far smaller than the part that is submerged. Upper text, corresponding with the top part of the iceberg: “bisexual identity”. Lower text, corresponding with the submerged part of the iceberg: “bisexual desire”.]
Just a friendly reminder that far more people experience bisexual desire and do not identify as bisexual (or indeed multisexual). Most of these people identify as heterosexual, others as gay, lesbian or unlabeled.
