Omnisexuality

Omnisexuality is a bi/multisexual identity defined as having a sexual attraction to all genders and sexes, with gender and/or sex as a factor in one's attraction.

Attraction
Omnisexuality is similar to pansexuality, the difference being that gender is a factor in the fact a omnisexual person's attraction, whereas it is not in a pansexual person's attraction (pansexuality is sometimes referred to as "gender blind" to reflect this). Omnisexuality and bisexuality are similar, the only difference being that bisexuality has a much more broad definition, compared to omnisexuality. Omnisexual is one of the relatively "new" identities, as the term was coined more recently than most other labels. Whilst the similarities between other bi/multisexual labels overlap with one another, the difference matters to some individuals as it said to help explain their experience with attraction.

The Flag
It is currently unknown who designed the flag, but evidence suggests that the lighter tones of colors on the ends might represent the gender spectrum since this identity acknowledges the existence of non-binary people. It is also likely that the pink in the flag represents different variations of femininity and attraction to women, the blue represents different variations of masculinity and attractions to men, and the dark stripe in the middle could represent attraction to people whose gender identity falls outside of the traditional Western gender binary.

Terminology
The word omnisexuality first appears in The Holy Barbarians, a book written by Lawrence Lipton. The book was originally published in 1959.
