(CNN) -

One of the stars of HBO's controversial new show "Girls" is vowing not to get naked for the camera.

Though Allison Williams' cast mate Lena Dunham has already been shown in a few, er, compromising positions this season, Williams told New York magazine's Vulture that if you're waiting for her to take it all off, you'll be waiting an awfully long time.

"Uh, I'm not planning on getting naked," the actress said during a recent interview, although she couldn't get into the details of how that's written into her contract."But, yeah, I'm not planning on it."

But pretending to self-pleasure on-screen, as she did in a recent episode? No big thing.

"I talked to [creator/director/star] Lena [Dunham] about it," she recounted. "It was just, I read it and, um, we just, yeah -- I mean, I shot the scene with Jorma, so I knew what came first, so that was really nice to shoot it in sequence. And so I could remember what I felt like after that scene with him and then, yeah. I'm sort of fascinated that it's being made into a thing, because I just looked at it as a part of my job."

Matter of fact, there were "scenes that were more difficult for me to do than that one, and it's interesting to me that people are fixating on it," she added. "I mean, little Sally Draper in 'Mad Men' did it before me, so listen -- I'm just entering her territory."
