“Been tatting myself up like crazy this month,” the 31-year-old actress captioned the post.
“I think it gives me a sense of control and ownership of a body that's often beyond my control,” added the star -- who has suffered from endometriosis -- in another post showing a close-up of the rose.
Dunham also shared a snap of a tattoo featuring two kewpie dolls delving into a barrel.
“These kewpies been on me a few weeks,” she shared.
The star is no stranger to sharing her body art on social media. Earlier this month, she posted a naked snap on Instagram, covering her private parts with emojis.
“At age 31, having been through hell and back with my health and other people's perceptions of my physicality, I feel deeply comfortable with the idea that this pear-shaped pot of honey is equally good for making people laugh and laying out like a Suicide Girl circa 2004,” she captioned the photo.
