The thing about chocolate..
If you want to improve your sex life, give yourself a chocolate treat. Chocolate has long been known as a sensual treat, and it has some scientific backing. The rush of endorphins produced by eating chocolates, particularly dark chocolates, is similar to the pleasurable feelings associated with a healthy sexual relationship. Chocolate also contains phenylethylamine which is known to stimulate the release of dopamine into the pleasure centers commonly associated with an orgasm.
