Note P — Chapter IX · LIBIDO SEXUALIS
Reading edition
Some women know how to train the sphincter cunni that it becomes as strong as the sphincter ani. This art is especially studied by the Parisian demi-mondaine, and it is said that therein lies a great deal of her much vaunted piquancy. The author had occasion to observe the regular voluntary contractions of the sphincter cunni during the vaginal examination of a young erotic woman of thirty years of age.
