There are many different types of orgasms, as some of us may know. One very interesting type is Exercise Induced Orgasm, or EIO. It was first documented by Alfred Kinsey and his colleagues in 1953, in the book Sexual Behavior of The Human Female. It has also been discussed at length in the studies and book, The Revolutionary Method for Better Sex Through Exercise, by Debby Herbewick PhD, who also coined the term “coregasm” as a moniker and who says it is most often a result of rigorous abdominal exercises in particular.
EIO is reported most often in women, however Herbenick found that 10 percent of men and women have experienced it at least once. Far more have reported EISP, or Exercise Induced Sexual Pleasure or sexual arousal during exercise.
There are several factors involved in the occurrence of a coregasm, including the type of exercise done, the number of reps or intensity of the exercise, and the combination of it with cardio exercise. The types of exercise that have been known to induce EIO include but are not limited to: yoga, climbing, hanging leg raises, chin ups, running, bicycling, swimming, sit ups, pull ups, rope climbing, and weightlifting. Studies have indicated they are more likely to occur easier when the sympathetic nervous system is engaged and the heart rate is up from 30 or more minutes or more of cardio exercise done prior. It has also been found that deeply fatiguing the core muscles is a contributing factor.
Instances of EIO are most often accidental. Exactly how they happen is unknown, however sex educators and pelvic floor therapists believe it’s related to the core and pelvic floor muscles’ roles in climax. Some believe it may also integrate the stimulation of nerve pathways.
In women pelvic floor contractions are believed to activate the clitoral network triggering orgasm similar in feeling to a vaginal orgasm. In men pelvic floor contractions are thought to stimulate the nerve-rich prostate, leading to climax—with or without ejaculation or even an erection. Men report EIO feels similar to prostate orgasms which are more intense and longer lasting than penile orgasms. Theoretically anyone can have them, but just how they happen and the intensity level depends on the individual.
Obviously where and when EIO is happening could have moral and legal implications, which is why most who have them try to reproduce a similar effect in masturbation or sex with a partner by using the same positioning and muscles as in EIO. There is still much mystery surrounding EIO, as is also the case for the G Spot orgasm. If you have experienced EIO yourself, rest assured, though, you are not alone.
