Last November Lena Dunham opened up about the physical and emotional ramifications of living with endometriosis, a physical condition where uterine tissue grows in other parts of the body in her Lenny newsletter.

While the actress has been open about having to deal with online bullies and hateful comments about her body, she hasn't let that get in the way of feeling comfortable in her own skin. The body-positive proponent has bared it all on her HBO TV show and recently starred in an unretouched lingerie ad in August with Girls co-star Jemima Kirke.
