Allison Williams' grandparents have seen her sex scenes in Girls.
The 26-year-old actress plays Marnie in the award-winning TV series created by Lena Dunham.
Reactions have been mixed to the amount of intimate encounters in the show, with some people claiming it goes too far.
However, Allison doesn't worry about what people think and admits even her father doesn't condemn her for the revealing scenes.
"Sometimes I feel like cringing, but [my dad is] so totally cool with the scenes that it puts me at ease - [my parents] have watched the show since it began," she explained to British magazine Look.
"My mom doesn't flinch. Even my grandparents have seen it and they're not shocked at all."
Allison insists the nudity isn't for shock value and hopes the gritty, vivid shots will help the younger generation feel more comfortable in their own love lives. She claims their portrayal of young women is accurate and that it is easier to relate to than other programmes.
"The way the show deals with sex and nudity is to explain that these young women are not leading wild, beautiful sex lives, but that a lot of it is very embarrassing and among the worst moments they're experiencing," she explained.
"A lot of young women have had these occasions where sex is uncomfortable and unpleasant, and not at all romantic - the way we're taught to think about it."
The brunette beauty feels she can relate to her alter ego and takes into account her flaws.
"She's a perfectionist, but she's also very insecure and scared about life, and her place in the world," Allison added. "She needs to know her friends are OK and not feeling down. I can identify with that."
