Lena Dunham's vagina has been seen by ''everyone'' who works on 'Girls'.

The 29-year-old creator, writer and star of the HBO series has revealed she's scrapped wearing nude patches while filming sex scenes for her hit TV show, meaning her private parts have been exposed to those people who work on the set.

She explained: ''I stopped wearing the nude patch after the first season of 'Girls'. There's not one guy who works on that show who hasn't seen the inside of my vagina.''

Lena said wearing the patch was uncomfortable and so she decided to film her sex scenes without one.

She told The Hollywood Reporter: ''This patch - you glue it over your vagina. It gets sweaty and always falls off. My male co-stars, at the end of the day, don't care. They wear a bag - like a penis bag.''

Meanwhile, the actress also recalled the most overtly sexist moment she's experienced since working in Hollywood.

She shared: ''I heard a guy on my show say into his microphone, 'I hate this job. I can't wait to be back on a show where there's a man at the helm'.

''Later, that same guy came up to me at lunch and said, 'You're really enjoying that buffet, aren't you?' He's the worst person alive. I hope he reads this, which he won't because he's drunk.''
