Female orgasms can last more than 20 seconds, while male orgasms last between 3 and 10 seconds on average. "Men's orgasms are thought to be more sudden and intense, while women's orgasms are long-lasting and less intense," say researchers at the American Psychological Association.

According to the latest research, women experience three types of orgasms. They are called "wave", "volcano" and "avalanche". While studying the orgasms of female volunteers, the researchers came to this conclusion and found that different types of orgasms affect different muscles of the pelvic floor, writes mirror.co.uk.

Based on the different names and models, James Pfauss, professor of neurology at Charles University in Prague, said the categories were defined by "how the pelvic floor muscles work during and after orgasm."

He added: “A wave-like orgasm was characterized by slow wave-like movements or continuous muscle contractions and relaxation during orgasm. Avalanche orgasms are characterized by tighter upper pelvic floor muscles that contract during orgasm and send tension downward. Volcano-type orgasm is manifested by the fact that the muscles of the lower part of the pelvis are more tense, but during orgasm all the muscles become very tense and then relax."

• Wave type orgasm

This orgasm manifests itself in waves or successive contractions.

• Avalanche orgasm

The location of this type of orgasm is in the upper pelvic floor muscle. The contractions that occur during it reduce the tension.

• Volcanic orgasm

During this type of orgasm, the tension is in the lower pelvic floor muscles, but during orgasm, all muscles tense and relax.

Professor J. Pfaus's team, whose findings were published in the "Journal of Sexual Medicine", have now focused on how women feel during these three types of orgasm. "We're doing a long-term study of women using The Lioness (a super-smart vibrator that measures pelvic floor muscle contractions in real time) to find out how these different types are subjectively experienced as orgasms, measuring the level of pleasure, investigating what stimulation is needed , to induce a certain type of orgasm,” the professor added.
