Subscribe To Our Newsletter! Newsflash: Heterosexual men report they are sexually attracted to women but not men. You guessed it: They report attraction to men, but not women, and they respond physically to erotic images that depict men and not women. But what about bisexual men? This inconsistency has baffled researchers and is at least partly responsible for the popular misperception that many bisexual men may not be truly bisexual.
I’m not confused: What people still don’t understand about bisexual men

A new study in the Journal of Preventative Medicine argues that the public health community has not paid enough attention to the unique needs of bisexual men. In Beyond the Bisexual Bridge , author William Jeffries suggests that men who have sex with men and women MSMW are often seen as transmitters of sexually transmitted infections STIs including HIV, and, more to the point, as the way in which certain diseases or epidemics jump from gay men to heterosexuals of both sexes. They are more likely to have early sexual debut, forced sexual encounters, and sex in exchange for money or something else of value.
Bisexuality in men
Bisexuality is romantic attraction, sexual attraction , or sexual behavior toward both males and females,    or to more than one sex or gender. The term bisexuality is mainly used in the context of human attraction to denote romantic or sexual feelings toward both men and women,    and the concept is one of the three main classifications of sexual orientation along with heterosexuality and homosexuality , all of which exist on the heterosexual—homosexual continuum. A bisexual identity does not necessarily equate to equal sexual attraction to both sexes; commonly, people who have a distinct but not exclusive sexual preference for one sex over the other also identify themselves as bisexual. Scientists do not know the exact cause of sexual orientation, but they theorize that it is caused by a complex interplay of genetic , hormonal , and environmental influences ,    and do not view it as a choice. Bisexuality has been observed in various human societies  and elsewhere in the animal kingdom    throughout recorded history.
The Kinsey Scale, developed in by Alfred Kinsey, Clyde Martin and Wardell Pomeroy, uses the numbers 1 through 6 to determine an individual's sexual preference. People who place at a 0 on the scale are considered heterosexual -- those with a score of 6 are considered gay or lesbian. Bisexual men and women are between a 1 and 5 on the scale. Aside from the formal test, there are several signs and behaviors that can indicate bisexuality in men. Counselor and nurse Kathy Labriola asserts that some men are circumstantial bisexuals, meaning they live as straight men most of the time, but will display attraction to the same sex when an opposite-sex partner is not available.
