"Girls" creator: "Sex isn't always glamorous"

(CBS News) The new HBO series "Girls" follows the lives of four young women in New York City. It already has women talking from coast to coast, particularly about the way the twenty-somethings' sexual experience is expressed in the series.

"Girls" is the brainchild of 25-year-old Lena Dunham. She's a writer, a director, executive producer and star on the show. Allison Williams, Jemima Kirke and Zosia Mamet co-star.

Thursday on "CBS This Morning," Dunham said it was her goal to show the "nitty gritty" of the sexual experience on the series.

"I often said that I I've felt a little unfairly duped by the sex I see on television," Dunham said. "I'm not saying this is every girl's sexual experience, but I am saying that sex isn't always glamorous, painful, it's embarrassing, it's complicated and I really wanted to see scenes where girls weren't wearing negligees and sighing."

"Girls" has been criticized and applauded for its depictions of sex. Dunham said she's careful about what's included in the show and gets guidance from people like Hollywood heavyweight Judd Apatow who is producing the show.

"I have a great brain trust of people around me...who let me know the line between honesty and aggressive and sort of -- how would I describe (it), a line between something that's honest and something that's sort of too in your face. The thing is, my litmus test for myself is 'Does this feel real for me or is this for shock value?' If I ever feel I'm doing the, 'Look, I'm on HBO, check out what I can do' thing, I pull back."
