Circumcision in the 1880s (back in the days when people were honest and circumcision served no other purpose than to impede masturbation and reduce the pleasure to be had from carnal acts):

Dr J.H. Kellogg, writing in 1888 in Plain facts for young and old: Embracing the natural history of hygiene and organic life:

In some countries females are also circumcised by removal of the nymphae. The object is the same as that of circumcision in the male.

Sir Richard Burton in the notes to the 2nd edition (1885) The Book of the Thousand Nights and a Nights:

Female circumcision is the proper complement of male circumcision, evening the sensitiveness of the genitories by reducing it equally in both sexes: an uncircumcised woman has the venereal orgasm much sooner and oftener than a circumcised man, and frequent coitus would be injurious to her health.
