Christina Aguilera is on this month's cover of Out magazine, and she talks about how she really feels about "kissing all the boys and the girls" and more.

The pop star says she felt really stifled making her debut album, which featured hits such as "Genie in a Bottle" and "What a Girl Wants." Her follow-up album, "Stripped," included the single "Beautiful," really set her free. Aguilera told Out’s Joshua David Stein, "On Stripped I was like, I don’t give a fuck."

Her upcoming album, "Bionic," has the single "Not Myself Tonight," which includes the line "I’m kissing all the boys and all the girls." So, is she just following the pop star bandwagon by embracing bisexuality? Aguilera explains, "I don’t get to kiss all the girls and the boys, but my husband knows that I get into girls. I think it’s fun to be open and play."

But she then clarifies, "I don’t think I could ever really be with a woman because that’s a lot of…" Aguilera pauses. "Yeah, there’s a lot of estrogen and I’m a lot to deal with when it’s that time of the month, so I can’t imagine it times two." She then shakes her head and adds, "And you know, I love dick. To be honest, that I cannot live without."

But don't discount her gay audience. Her friend and collaborator Sia explains, "I feel like Christina’s probably supporting the majority of the lesbian scene in Los Angeles because she really only works with gaylords, like her dog walker, her personal trainer, her cowriters.” As Stein puts it, “Bisexual or not, Aguilera is queer in the word’s most literal sense."
