It took greater pain stimulus for them to feel the pain.

Beverly Whipple

Beverly Whipple is Professor Emerita at Rutgers University and a professional author and sexologist. She is a co-author of the publication The G Spot and Other Recent Discoveries About Human Sexuality. Following a career in nursing, much of her academic work has been concerned with the enhancement of female sexual function. In 1981, she was co-author of Addiego et al.'s "Female ejaculation: a case study." The paper was presented in The Journal of Sex Research and includes the first published instance of the term "G-Spot". Following the book, Whipple continued to publicize her work, including a 9 min video made in 1981 Orgasmic Expulsions of Fluid in the Sexually Stimulated Female. In 1984, the Journal of Sex Research described the debate surrounding female ejaculation as 'heated'. Her techniques include using FMRI scans to gather evidence on what is happening in the brain. Her animal experiments contributed to the isolation of the vasoactive intestinal peptide and the discovery that orgasms can be rerouted to the brain via the vagus nerve without using the spinal cord, thus enabling females with spinal cord injury to achieve orgasm by psychological stimulation alone.
