No sex necessary: Women have orgasms at the gym, study shows
By Jeanna Bryner, LiveScience

Women may not need a guy, a vibrator, or any other direct sexual stimulation to have an orgasm, finds a new study on exercise-induced orgasms and sexual pleasure. The findings add qualitative and quantitative data to a field that has been largely unstudied, according to researcher Debby Herbenick, co-director of the Center for Sexual Health Promotion at Indiana University. For instance, Alfred Kinsey and his colleagues first reported the phenomenon in 1953, saying that about 5 percent of women they had interviewed mentioned orgasm linked to physical exercise. However, they couldn't know the actual prevalence because most of these women volunteered the information without being directly asked.
