in producing sexual
excitement.

[206] A correspondent, to whom the idea was presented for the first time,
wrote: "Henceforward I shall know to what I must attribute the
bliss--almost the beatitude--I so often have experienced after traveling
for four or five hours in a train." Penta mentions the case of a young
girl who first experienced sexual desire at the age of twelve, after a
railway journey.

[211] In the Appendix to volume iii of these _Studies_, I have recorded
the experience of a lady who found sexual gratification in this manner.

[212] Dr. J.G. Kiernan, to whom I am indebted for a note on this point,
calls my attention also to the case of a homosexual and masochistic man
(_Medical Record_, vol. xix) whose feelings were intensified by
tight-lacing.

[213] Some women are also able to produce the orgasm, when in a state of
sexual excitement, by placing a cushion between the knees and pressing the
thighs firmly together.

[214] _Lecons sur les Deformations Vulvaires_, p. 64. Martineau was
informed by a dressmaker that it is very frequent in workrooms and can
usually be done without attracting attention. An ironer informed him that
while standing at her work, she crossed her legs, slightly bending the
trunk forward and supporting herself on the table by the hands; then a few
movements of contraction of the adductor muscles of the thigh would
suffice to produce the orgasm.

impulse to self-flagellation on the nates with a rod, for the sake of
sexual excitement, from the age of 6. (_Rivista Mensile di Psichiatria_
