Well some people would say why would you limit yourself to half the candy in the box!\n\nBut there have actually been studies of men who think of themselves as bisexual as far as what gets them aroused, and nearly all of the men in the study had s distinct preference as far as what they reacted to.  And most in the study who said they were Bi responded more positively to females, although a few seemed to prefer men.\n\nThe same study was performed on heterosexual and gay males and they found that the heterosexuals became more aroused when presented with images of women and gay men tended to react much more strongly to men, as you would expect.\n\nIn my experience women who are bi get a much warmer reception (except among lesbians) and men who are are sometimes shunned by both Gay and Straight people.  \n\nI will try to find an article about the study and post it below.
