Naturally there are many things every man and woman should know about female orgasms. This is a good list to start with. These five facts about female orgasms were discovered by neuroscientist Barry R. Komisaruk, endocrinologist Carlos Beyer-Flores, and sex researcher Beverly Whipple in their research (get their book The Science of Orgasm).

• It isn’t easy
  It takes about 20 minutes of clitoral or G-spot stimulation for most women to hit the jackpot. An average intercourse doesn’t even last that long. The researchers also estimate that 24 to 37 percent of women can’t climax at all. This is mostly because smoking, drinking, emotional disorders, medications, and menopause.
• You can get help
  Fortunately if you can’t climax, there’s hope for you. Cognitive behavioral therapy, testosterone treatments, the herb ginkgo biloba, and the nutritional supplement ArginMax (which includes Korean ginseng, ginkgo biloba, vitamins, minerals, and an amino acid) have been shown to improve sexual satisfaction.
  
• Pleasure for procreation
  Some researchers believe that having an orgasm during sex increases the chance of conception. The theory: Oxytocin, a hormone released in peak levels during orgasm, causes uterine contractions that coax sperm toward the egg.
• Mastrubation is good for you
  Besides its obvious perks, masturbating is good for your health. Studies show that orgasm can reduce sensitivity to pain, relieve menstrual cramps, and alleviate stress—possibly due to a surge in oxytocin and dopamine.
• Orgasm as treatment for hysteria
  From ancient Greece to Freud’s time, doctors stimulated orgasms in women via “medical massage” to treat the catchall female ailment known as hysteria. In the late 1800s, the vibrator was designed for the same purpose.
