Fanny Hill, or memoirs of a woman of pleasure. Ohh, yes. That, along with My Life and Loves, by Frank Harris, both generated a love of Victorian erotica. Many, many stroke sessions to both. Both were more arousing to me than D.H.Lawrence and Henry Miller.
I had a similar experience with Fanny Hill. I found a copy in a second hand book store recently and bought it for a couple of bucks. It seems to have lost its magic effect on my dick after all these years.
