If you love your husband
Get yourself circumcised
Because the germs under your prepuce
Can reach his mouth when he pleasures your clitoris
And cause him oral cancer
The culprit is Human Papilloma Virus
Found in the prepuces of the uncircumcised
Muslimahs for Circumcision
The meme was shared on Facebook in Muslimahs for Sunna and Muslimahs for Female Circumcision according to Twitter screenshots. According to this website, a facebook group called "Islamic Female Circumcision" also had this meme, and it was deleted by Facebook.
I tried searching, and mainly found pages discussing whether male circumcision affects HPV.
