Vaginal erotic sensitivity was investigated in a group of 48 coitally experienced volunteers by means of systematic digital stimulation of both vaginal walls. It was found that 45 subjects reported erotic sensitivity located in most cases on the upper anterior wall, and of those, 30 (66.7%) either reached orgasm or requested to stop stimulation short of orgasm. This study supports previous findings indicating that the vagina of most women has a zone (or zones) of erotic sensitivity whose appropriate stimulation can lead to orgasm; it does not support, however, the particular location and characteristics of the vaginal erogenous zone described by other authors.
