Lena Dunham is all about oversharing, so it should come as no surprise that her sex life has been an open book.

Dunham has been promoting her new book, Not That Kind of Girl and just to show off how social media savvy she is, she did a series of YouTube videos to answer some fan questions. In one response to a fan’s question about bad sex, Dunham revealed that she didn’t even think about enjoying sex until she was 25.

“I don’t think I ever even thought about whether I was enjoying sex ‘till I was like 25,” she explained. “Because I was so worried about whether other people were enjoying sex with me that it never would have occurred to me that it was an act I was supposed to receive any pleasure from.”

As the Daily News points out, she added that before her current boyfriend, “who’s a lovely, lovely person, I had a train of the most disastrous, despicable, van-dwelling monsters in my bed.”

Dunham is currently dating fun. guitarist Jack Antonoff. She recently showed off her platinum blonde bowl-cut hairstyle, which is on full display in her video series. She is also the creator and star of HBO’s Girls, which will be starting its fourth season next year.

You can pick up a copy of Not That Kind Of Girl on Sept. 30.
