George Ryley Scott was a prolific British author of books about sex, however he also wrote on rabbit keeping, poultry breeding, bathing, corporal punishment, and the act of writing itself.
Scott’s Encyclopedia of Sex aimed to “provide in one volume and in concise form, a complete epitome of all the knowledge at present available in the vast field of sexology”, covering topics as diverse as bearded women, dreams (erotic), honeymoon impotence, masturbation (symbolical), serpent worship and vampirism.
Consult the encyclopaedia to expand your vocabulary, however bear in mind that Scott does not “lay any claim to infallibility”.
Scott also produced a helpful guide for those concerned with the effect of WWII on their sex life, including advice on “The Trend towards Divorce” and “Menstrual Troubles due to War Conditions”:
