Well, without looking around a bit in pubmed, I can only speak from experience.
I don't know any bi boys. I know lots of bi girls. And most bi girls I know are just a smidge gay or straight ... some like boys just a bit more and some like girls just a bit more.

Only 1/3 of lesbian respondents stated that they were 100% attracted to women. The remainder ranged from 50 to 95 percent attracted to women, tending strongly toward a predominance of homosexual over heterosexual feelings. In contrast, bisexual respondents covered the entire range of feelings of sexual attraction, excluding both extremes of 100% attraction to either sex. Homosexual and heterosexual feelings were not equally distributed among bisexual respondents; 61% reported predominantly homosexual feelings while 22% reported predominantly heterosexual feelings. In sum, exclusively homosexual feelings were unique to lesbian respondents and predominantly heterosexual feelings were unique to bisexual respondents. However, most lesbian respondents and most bisexual respondents shared a nonexclusive preference for women.
