But that's something she's trying to change...
"Frankly, no one had ever asked me before," the True Blood starlet tells V magazine's Transformation Issue (hitting stands July 7) of her 2010 bisexual admission. "My sexuality is something I'm completely comfortable with and open about. There's a lot of prejudice toward us but the more people talk about it, the less of a big deal it will be. And that will be better for everyone."
While Paquin's True Blood character Sookie Stackhouse has yet to engage in any same-sex loving, she has had plenty of steamy screen time with costar and real-life hubby Stephen Moyer. But it's not as awkward as you might think.
"Maybe it should be weird, simulating sex with your husband in front of people," she admits. "But it's really not. When it's a love scene with someone you actually love, there's no feeling like, 'Can I touch him here, can I touch him there?' You know what your boundaries are—or what they aren't, I suppose."
Another sexy something she's cool with? Fans worshipping Mr. Moyer.
"There is probably something wrong with me, but I find it amusing to watch these men and women fawn all over him," Paquin says. "It's not like anyone's really trying to do anything inappropriate. They just want him to hug them...or bite them."
Or, as Moyer recently told Men's Health, "I get to sign boobs a lot. I get to bite boobs, occasionally, when I'm allowed."
