Cameron Diaz, Raúl Esparza, Michelle Rodriguez, Fergie, Christina Aguilera and Demi Lovato are just a few examples of those who've had heterosexual and same-sex experiences and attractions, signifying bisexuality. While nearly just 16 percent of U.S. residents indicated they're bisexual, a whopping 31 percent of individuals under the age of 30 consider themselves something other than heterosexual, according to new research.

Based on results from YouGov based on Alfred Kinsey's 'Kinsey Scale,' which gauges individuals on a range of sexual dispositions from "exclusively heterosexual" at 0 to "exclusively homosexual" at 6, approximately 78 percent of Americans indicated they were heterosexual, while 4 percent said they're completely homosexual.

"I've never walked the carpet with anyone, so they wonder, 'What does she do with her vagina?' ... I've gone both ways. I do as I please. I am too f*cking curious to sit here and not try when I can. Men are intriguing. So are chicks," 37-year-old actress Michelle Rodriguez once told Entertainment Weekly when discussing her bisexuality.

Approximately 16 percent of Americans indicated that they fall somewhere in the middle, with 10 percent saying they were more heterosexual-leaning, while 3 percent placed themselves squarely in the middle and 3 percent were homosexual-leaning.

Younger Americans, namely millennials, are less likely than older Americans to firmly place themselves in a defining category.

Eighty percent of all Americans identify as completely gay or heterosexual, but the same can only be said of 66 percent of millennials under the age of 30. Also, 29 percent of those under 30 considered themselves to be bisexual. Younger people are more likely to acknowledge fluidity when discussing sexual attraction. In addition to younger Americans, 24 percent of individuals aged 30-44 placed themselves somewhere on the bisexuality scale, which is significantly higher than 8 percent or less for those over the age of 45.

The report also showed that 12 percent of self-described heterosexuals have had sexual experiences with the same sex. Fifteen percent of heterosexual women and 8 percent of heterosexual men said they'd had sexual encounters with individuals of the same sex, revealing straight women were twice as likely as men to have same sex encounters. When a similar study about sexual flexibility was done in the U.K., it was found that nearly half of Britons under the age of 25 identified as bisexual on some level.
