Getting busy under the sheets offers a slew of health benefits including stronger pelvic floor muscles, which not only increases pleasure, but also improves bladder control. Having an orgasm can relieve nasal congestion (that beats Benadryl any day!), and when the hormone oxytocin gets released, it can help you have a better night's sleep.
Regularly rolling in the hay (once or twice a week) can also boost your immunity and reduce your chance of catching a cold. And for the greatest benefit of all, women who have sex live longer than those who don't.
