Ok how do you "benignly" circumcise a female?
You take off the prepuce, same as in a male circumcision.
There are many variants of female circumcision. The mildest is the rough equivalent of male circumcision, removal of the prepuce. Most males who have undergone this procedure are not particularly traumatized by it.
The most extreme are the rough equivalent of removal of testes and penis, not with regard to fertility but with regard to potential for sexual pleasure. I would think this would be traumatic for anyone.
