1. In a 2001 study from the Queen's University in Belfast, Ireland, men who had sex to the point of orgasm three times a week cut their risk of heart attack or stroke in half.
2. Research suggests that orgasms can lower the rate of prostate cancer and reduce the risk of certain sex-organ-related diseases.
3. The main difference in how men and women orgasm is that men reach a point where they can't hold back from an orgasm. On the other hand, women can lose an orgasm even as it's happening.
4.  All kinds of age-defying events happen as three hormones (beta endorphin, prolactin and oxytocin) spill out of the brain during orgasm to promote happiness, diminish pain and increase relaxation.
5. Masters and Johnson found that both men and women burn 7 to 25 calories per orgasm.
6.  Most orgasmic headaches are not serious. However, a severe headache during orgasm can signal a serious medical problem such as a brain aneurysm or tumor, and should be checked by a doctor.
7. Scientists have found that the chemicals and pheromones in male sweat increase sexual desire in women.
8. A long-term study of 3,500 people in Scotland found that regular sex may shave roughly 4 to 7 years off your physical appearance. In addition to greater confidence and self-esteem, sex increases the body's production of human growth hormone, which improves muscle tone.
9. For men and women, morning seems to be the best time for orgasm. Testosterone levels are higher, blood flow is greater and you have more energy.
10. Many men feel sleepy after an orgasm because the body relaxes, blood pressure lowers, and muscles let go of tension.
11. Many people find that the more they focus on having an orgasm, the more difficult it is to have one. It's more important to focus on the overall pleasure of sexual activity. Even without an orgasm, sex still feels good.
12. During an orgasm the uterus contracts. In some women, this can cause cramping for up to an hour.
13. Men with delayed ejaculation have trouble with orgasm, either taking longer to reach it, reaching it only through masturbation or being unable to reach it at all. To avoid embarrassment they might fake orgasm.
14. Too much stress saps away a person's libido by affecting hormones and mood, and by interfering with the quality time that helps a couple stay connected.
15. The majority of women have an orgasm more easily with direct stimulation to the clitoris.
16. During orgasm, the muscles in a woman's pelvis, anus, uterus and vagina contract, causing a throbbing feeling. Muscles throughout the rest of the body, often in the face, legs and back, also begin to contract.
17. You can have an "energy orgasm" by using your imagination, muscle tension and breath.
18. In some cases, women who orgasm between 1 minute before and 45 minutes after their partner's ejaculation have a higher tendency to retain sperm compared to those who don't have an orgasm.
19. Because orgasms trigger pelvic contractions and the release of oxytocin (the hormone that induces labor contractions), there's a possibility that orgasms may start labor in women at risk for pre-term labor or in women who are in late-term pregnancy. However, in most cases, having sex and orgasming while pregnant is perfectly safe.
20. This is false. The intensity of an orgasm may vary from person to person, but people usually realize that they're having an orgasm.
