This could involve someone who "experimented" with a same-sex relationship when they were younger and are now in a long-term heterosexual relationship, or could be someone who is actively dating within either gender. Another "form" of bisexuality could be someone who would be labeled as "monosexual" (either strictly heterosexual or homosexual), but might fantasize or think about being in a relationship or being sexual with someone of the opposite gender (opposite in relation to the one they are labeled as being attracted to). These people might consider themselves bisexual, even though they do not act upon it. .
Transgendered and transsexual people can also blur the lines of sexual orientation when it is applied to bisexuality. Because of their unique place within gender roles, transgendered and transsexuals make it hard to categorize them into a certain sexual orientation. The confusion lies around whether to categorize their sexuality based on their natal (genetic/birth gender) sex or based on their "new" identity, either post-operative, post-transition or what they consider themselves to be (male or female). "What if a non-operative transsexual man [female by birth, transitioned into living as a man with female genitals] has as a partner a postoperative transsexual man [female by birth, living as a man, including surgery to become "male"]? Is this a gay relationship? A straight one? Are any of these people bisexual? And most significantly, can the term bisexuality have any meaning at all when gender is deconstructed?" (Denny and Green, 89).
Common problems bisexuals face (Biphobia):.
One of the main problems that bisexual people face is the idea that bisexuality is not a "real" sexual orientation. This belief is held by not only the heterosexual community but by the homosexual community as well. Many people think of bisexuality as a transition into becoming gay or as a denial of oneself being gay.
