FB has some strange policies around what is and isn’t “pornographic.” Highly sexualized images of women, rape “joke” pages, and so forth are allowed.
Images educating people on where the clitoris is, or images of breastfeeding are not.
Check this post out by MotherWiseLife on being blocked, having photos removed, and having her own account shut down (the one connected to this page) and share it. On your FB.
As Sheryl Sandberg would say, LEAN IN.
If FB allows the page “Best Ass Fap” surely they can handle an image of the vulva for educational purposes.
