London - For nearly four in ten women, sleep isn’t just about recharging the batteries – it seems it’s also a source of great pleasure.
US researchers found 37 percent of women had experienced a “sleep orgasm” by the age of 45.
By contrast only half had enjoyed an orgasm during normal sex.
According to the study, so-called nocturnal orgasms can occur in females aged between the teenage years and the 50s, and whether they were single or married.
Meanwhile 83 percent of men participants had experienced the phenomenon, although mostly when in their teens.
