The "wearing out of the vagina" is the most ridiculous thing I have heard in some time. In fact, the opposite is true.
Sex, will literally keep your entire body feeling and looking younger:
Sex helps increase the blood flow to your brain and to all other organs of your body. Increased heart rate and deep breathing accounts for the improvement in circulation. As fresh blood supply arrives, your cells, organs and muscles are saturated with fresh oxygen and hormones, and as the used blood is removed, you also remove waste products that cause fatigue and even illness.
Sex helps lower the overall cholesterol level. Perhaps more importantly it tips the HDL/LDL (good/bad) cholesterol balance towards the healthier HDL side.
With arousal and orgasm oxytocin levels rise. They spike 3 to 5 times higher than usual just before orgasm. In fact it is oxytocin that triggers the orgasm and is an incredible pain reliever.
Endorphin levels increase which is a natural mood elevator and strees reliever.
The hormone DHEA promotes sexual excitement and increases in response to it. DHEA helps balance the immune system, improves cognition, promotes bone growth, and maintains and repairs tissues, keeping your skin healthy and supple. It may also contribute to cardiovascular health and even function as antidepressant.
Regular sexual activity boosts testosterone and estrogen levels in both men and women. Besides boosting your libido testosterone fortifies bones and muscles. Some physicians suggest that testosterone keeps hearts healthy and good cholesterol high. Sex increases womens estrogen levels keeping vaginal tissues more supple and also protecting against heart disease.
