8. Sex Reduces Prostate Cancer Risk
Frequent ejaculations, especially in 20-something men, may reduce the risk of rostate cancer later in life, Australian researchers reported in the British Journal of Urology International. When they followed men diagnosed with prostate cancer and those without, they found no association of prostate cancer with the number of sexual partners as the men reached their 30s, 40s, and 50s. But they found men who had five or more ejaculations weekly while in their 20s reduced their risk of getting prostate cancer later by a third. Another study, reported in the Journal of the American Medical Association, found that frequent ejaculations, 21 or more a month, were linked to lower prostate cancer risk in older men, as well, compared with less frequent ejaculations of four to seven monthly.
9. Sex Strengthens Pelvic Floor Muscles
For women, doing a few pelvic floor muscle exercises known as Kegels during sex offers a couple of benefits. You will enjoy more pleasure, and you'll also strengthen the area and help to minimize the risk of incontinence later in life. To do a basic Kegel exercise, tighten the muscles of your pelvic floor, as if you're trying to stop the flow of urine. Count to three, then release.
10. Sex Helps You Sleep Better

The oxytocin released during orgasm also promotes sleep, according to research. And getting enough sleep has been linked with a host of other good things, such as maintaining a healthy weight and blood pressure. Something to think about, especially if you've been wondering why your guy can be active one minute and snoring the next.
