She get's really candid at times about sexual experiences but she doesn't seem shameful that she's sharing such intimate details of her love life. If you've been reading the newspaper or watching entertainment news - she's been in the headlines lately but not for publishing a great book but for over-sharing and folks pointing the "Celebrities Can't Make Mistakes" Stick at her about an experience with her little sister and her vagina that didn't go over to well. But if those types of things don't bother you (because you know she was a child doing these things) - She also covers funnier topics about dieting, body image, love, etc. Though her point was probably not to do anything but entertain us and close the door on people constantly asking - "Who exactly is Lena Dunham"? but she opened a few doors of thought and reflection that I am happy she did.
If you haven't yet - pick the book up and check it out for yourself,
