I am reading books about the Victorian era and Queen Victoria and thought about this. I know about female hysteria so I understand there was some sort of awareness of the female orgasm. Serious answers please! Not asking for anything NSFW.
I dont have the library on hand (due to some thanksgiving travel) but yes, the victorians were well aware of sexual pleasure and the female orgasm (and thought of it as essential!). The place you want to start your research is Therese O'Neills Unmentionable: The Victorian Lady's Guide to Sex, Marriage, and Manners and Fern Riddels The Victorian Guide to Sex: Desire and deviance in the 19th century
