Have you ever heard that song called Sexual Healing? It’s not just a metaphor. Sex can actually heal. It can heal your body and mind and prevent lots of diseases.

Some say it’s the first medicine ever known to man and it should be administered daily. Sounds too good to be true? Let’s discover the four reasons for which a man should have sex each day.

Great form of exercise
Making love is a form of physical activity. During intercourse, the physiological changes in your body are consistent with a workout. You must have noticed that the respiratory rate rises, which means you get tired. Hence, you burn calories. If you have sex three times a week for 15 minutes (but we know you can do better than that) you’ll burn about 7.500 calories in a year. That’s the equivalent of jogging 75 miles! Heavy breathing raises the amount of oxygen in your cells, and the testosterone produced during sex keeps your bones and muscles strong.

Pain relief
The “Honey, not today, I have a headache” cannot be an excuse any more. During sex, both male and female bodies produce endorphins, hormones that act as weak painkillers. A study conducted by Gina Ogden showed that during sexual stimulation and especially during orgasm, we don’t feel pain. If she finds another excuse, remind her that sex is good for her entire reproductive system, because it trains the PC muscle, which keeps the reproductive organs in shape. In women, sex can also increase fertility, postpone the menopause and relieve PMS symptoms.
Prostate protection

Most of the fluid you ejaculate is secreted by the prostate gland. If you stop ejaculating, the fluid stays in the gland, which tends to swell, causing lots of problems. Regular ejaculation will wash those fluids out and ensure the well being of your prostate until old age. Problems may also occur when you suddenly change the frequency of ejaculations.

Prevents erectile dysfunctions
Fifty per cent of men older than 40 suffer from erectile dysfunctions and all young men fear the moment when they won’t be able to get it up any more. The best medicine against impotence is…sex. An erection keeps the blood flowing through your penile arteries, so the tissue stays healthy. Plus, doctors compare an erection to an athletic reflex: the more you train the more capable you are to perform.

Stress relief
It’s a scientific fact: sex can be a very effective way of reducing stress levels. During sex your body produces dopamine, a substance that fights stress hormones, endorphins, aka “happiness hormones” and oxytocin, a desire-enhancing hormone secreted by the pituitary gland.

That's very very true. I myself observed that married couples who don't have sex regularly aged quickly compared to those who do it regularly.
Also I discovered that couples who have sex regularly are more relaxed and happy. They appear more healthy and full of life compared to those who don't.
Nature is indeed a medicine on it's own.
