Historically, bisexuality has largely been free of the social stigma associated with homosexuality, prevalent even where bisexuality was the norm. In Ancient Greece pederasty was not problematic as long as the men involved eventually married and had children. In many world cultures, homosexual affairs have been quietly accepted among upper-class men of good social standing (particularly if married), and heterosexual marriage has often been used successfully as a defense against accusations of homosexuality. On the other hand, there are bisexuals who marry or live with a heterosexual partner because they prefer the complementarity of different sexes in cohabiting and co-parenting but have felt greatly enriched by homosexual relationships alongside the marriage in both monogamous and "open" relationships.
Same-sex marriage became legal in Norway on 1 January 2009 when a gender-neutral marriage bill was enacted after being passed by the Norwegian legislature, the Storting, in June 2008. Norway became the first Scandinavian country and the sixth country in the world to legalize same-sex marriage. Gender-neutral marriage replaced Norway's previous system of registered partnerships for same-sex couples. Couples in registered partnerships are able to retain that status or convert their registered partnership to a marriage. No new registered partnerships may be created.
People who identify as transgender or transsexual are usually people who are born with typical male or female anatomies but feel as though they’ve been born into the “wrong body.” For example, a person who identifies as transgender or transsexual may have typical female anatomy but feel like a male and seek to become male by taking hormones or electing to have sex reassignment surgeries.
Genderqueer or non-binary identities, which are not exclusively masculine or feminine but instead may be agender, androgynous, bigender, pangender, or genderfluid, exist outside of cisnormativity. Bigender and androgynous are overlapping categories; bigender individuals may identify as moving between male and female roles (genderfluid) or as being both male and female simultaneously (androgynous), and androgynes may similarly identify as beyond gender or genderless (postgender, agender), between genders (intergender), moving across genders (genderfluid), or simultaneously exhibiting multiple genders (pangender). Limited forms of androgyny are common (women wearing pants, men wearing earrings) and are not seen as transgender behavior. Androgyne is also sometimes used as a medical synonym for an intersex person. Genderqueer identities are independent of sexual orientation.
In some cases bisexuality is actually a form of fitness favored by evolution. For example, in the absence of male whiptail lizards (Cnemidophorus), females reproduce by pairing up with each other. During the breeding season females will take turns switching between "male" and "female" roles as their hormones fluctuate. Estrogen levels are high during ovulation ("female" role) and much lower after laying eggs ("male" role). While in the "male" role, a female lizard will mount another in the "female" role and go through the motions of sex to stimulate egg-laying. The hatchlings produced are all female. This all-female species has evolved from lizards with two sexes, but their eggs develop without fertilization (parthenogenesis). Female whiptail lizards can lay eggs without sex, but they lay far fewer eggs than if they engage in sexual stimulation by another female.
The Pride and its associated events are organized by the Associação da Parada do Orgulho de Gays, Lésbicas, Bissexuais e Travestis e Transsexuais, since its foundation in 1999. The march is the event's main activity and the one that draws the biggest attention to the press, the Brazilian authorities, and the hundreds of thousands of curious people that line themselves along the parade's route. In 2009, 3.2 million people attended the 13th annual Gay Pride Parade.
Arranging a civil partnership registration with a British consulate generally takes at least a month and must be done in person in the country where the consulate is located. Those whose British National (Overseas) passports have expired or who no longer hold a valid passport need to apply for a renewal before arranging a civil partnership registration with a British consulate.
