Actress Rose McGowan says her Conan the Barbarian co-star Jason Momoa has an epic ass.

The 37-year-old McGowan is best known for her role playing Paige Matthews for four seasons on the supernatural television series Charmed.

She stars as the powerful witch Marique in Conan the Barbarian, which opens in theaters on Friday, August 19.

In an interview with gay glossy The Advocate, McGowan, who was raised in a gay-friendly household, said she wishes she was bisexual.

“I disappoint myself,” McGowan said. “I've never even kissed a girl. Isn't that funny? The girls I think are cute look like guys, but then I think, 'But if they open their shirt, they'll have breasts.' You know that guy Brad [Goreski], who was Rachel Zoe's assistant? I'd be attracted to a girl version of him. … I'd be stoked to do a lesbian love scene. When asked if I've kissed a girl, I could finally say, 'Why, yes, I have. And I got paid.”

She added that she can only handle straight people in small doses: “[E]n masse they make me uncomfortable – especially a bunch of straight men.”

But maybe she would be more comfortable if the men looked like her Conan the Barbarian co-star Jason Momoa.

“Jason's ass is epic. When I saw his backside naked, I was like, 'Oh, my.' He's got a beautiful body, because it's not all Mr. Steroid. He looks raw and masculine.”
