Spontaneous orgasms

Orgasms can be spontaneous, seeming to occur with no direct stimulation. Occasionally, orgasms can occur during sexual dreams (see Nocturnal emission).

The first orgasm of this type was reported among people who had spinal cord injury (SCI). Although SCI very often leads to loss of certain sensations and altered self-perception, a person with this disturbance is not deprived of sexual feelings such as sexual arousal and erotic desires. Thus some individuals are able to initiate orgasm by mere mental stimulation.

Some non-sexual activity may result in a spontaneous orgasm. The best example of such activity is a release of tension that unintentionally involves slight genital stimulation, like rubbing of the seat of the bicycle against genitals during riding, exercising, when pelvic muscles are tightened or when yawning or sneezing.

It was also discovered that some anti-depressant drugs may provoke spontaneous climax as a side effect.There is no accurate data for how many patients who were on treatment with antidepressant drugs experienced spontaneous orgasm, as most were unwilling to acknowledge the fact.
