When I think of rape, I classify it as a violent act, including domination even though it's sexual in nature. The person who did this to you should be punished, not you punishing yourself. If it wasn't you, it would have been your other siblings or someone else.
Female circumcision or I like to term it genital mutilation because that's what it is......it's a real pet peeve of mine because this is forced upon healthy young women and girls in some countries. It's a twisted belief steeped in deep cultural roots, that women need to be altered in order to control them. You're punishing yourself further and that's not right.
Why should you continue suffering from what happened in the past- but I'm not saying you shouldn't deal with it. I doubt your abuser is suffering. Punishing and hurting yourself is just continuing the abuse you've already suffered.
I don't know what twisted person put up instructions for genital mutilation, but that so wrong. The internet can be very helpful but it's also a deep cesspool of horrible things as well. I hope one day soon you can stand up and realize you deserve some peace and contentment (((Can't Stop Crying))).

Honor your body and yourself.
