A dry orgasm is a sexual climax that does not result in ejaculation. The term only refers to orgasms experienced by males.
Boys who masturbate before the age of puberty will usually only experience dry orgasms, if they experience any climax at all. Boys who experience dry orgasms can often produce multiple orgasms, as the need for a rest period is reduced. Some males consider dry orgasm to feel uncomfortable or even painful, while other men practice to achieve multiple orgasms some of which by necessity must be dry.
Dry orgasms may also occur in men who ejaculate multiple times in a short period such as an hour, after the first few ejaculations have used up the available stored seminal fluid. This condition is self-limiting, as after a few hours the supplies of seminal fuid will be replenished by the prostate gland and seminal vesicles.
Men who have had their prostate removed (usually as a result of cancer) may also experience dry orgasms.
Another cause of dry orgasms is retrograde ejaculation, where the semen flows into the urinary bladder, rather than through the urethra to the outside.
The term "dry orgasm" is also used for a form of mind-body orgasm where the mind experiences orgasm without attempted ejaculation. This type of dry orgasm is one of the goals of Tantric sex.
