Sexuality is but one of many areas where religious and civic authority interact; definitions of the purpose of marriage is another. In one view, the purpose of marriage is to ensure successful procreation and child rearing. In another, marriage provides a—and perhaps “the”—fundamental building block of stable communities, with procreation as an incidental by-product. A third perspective holds that marriage is an instrument of societal domination and so is not desirable. A fourth is that relationships between consenting adults should not be regulated by the government. Although most religions subscribe to just one of these beliefs, it is not uncommon for two or more viewpoints to coexist within a given society.

In 1995, Jill Sobule sang about bi-curiosity in her song "I Kissed a Girl", with a video that alternated images of Sobule and a boyfriend along with images of her with a girlfriend. Another song with the same name by Katy Perry also hints at the same theme. Some activists suggest the song merely reinforces the stereotype of bisexuals experimenting and of bisexuality not being a real sexual preference. Lady Gaga has also stated that she is bisexual,[114] and has acknowledged that her song "Poker Face" is about fantasizing about a woman while being with a man.[115]
Many non-human animal species exhibit bisexual behavior.[10][11][12] Examples of mammals that display such behavior include the bonobo (formerly known as the pygmy chimpanzee), orca, and the bottlenose dolphin.[10][11][12][136] Examples of birds include some species of gulls and Humboldt penguins. Other examples of bisexual behavior occur among fish and flatworms.[136]

Another parade, this time billed as an international event, was scheduled to take place in the summer of 2005, but was postponed to 2006 due to the stress on police forces during in the summer of Israel's unilateral disengagement plan. In 2006, it was again postponed due to the Israel-Hezbollah war. It was scheduled to take place in Jerusalem on November 10, 2006, and caused a wave of protests by Haredi Jews around central Israel.[54] The Israel National Police had filed a petition to cancel the parade due to foreseen strong opposition. Later, an agreement was reached to convert the parade into an assembly inside the Hebrew University stadium in Jerusalem. June 21, 2007, the Jerusalem Open House organization succeeded in staging a parade in central Jerusalem after police allocated thousands of personnel to secure the general area. The rally planned afterwards was cancelled due to an unrelated national fire brigade strike which prevented proper permits from being issued. The parade was postponed once more in 2014, as a result of Protective Edge Operation.
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.
