By definition, wet dreams are when someone of either sex orgasms involuntarily while asleep, without any conscious manual stimulation. While male wet dreams result in ejaculation, female wet dreams typically result only in an orgasm.

Sleep orgasms in women are not as common as in men, but they still occur. Strangely, it's more common for women to have sleep orgasms later in life, possibly because it's easier to reach orgasm with experience and age.

Porn, meds or both?

According to Tatyana Dyachenko, a relationship expert, psychologist and sex therapist, sleep orgasms in women occur when they're most relaxed.

"It's believed that they happen because the body is in a relaxed state whilst we sleep, which means there is an increase of blood flow to certain areas of the body," Dyachenko said. "Combine that increased blood flow, especially to the genital area, with an erotic dream and the likelihood is a sleep orgasm. Going to bed relaxed has also been known to increase the chances of experiencing one."

Dyachenko said watching porn or a sexy movie
