Berries :

Not only is a handful of juicy berries inherently sexy, it can also serve a practical purpose in the bedroom. Strawberries are high in the B vitamin folate, which helps prevent birth defects, and vitamin C, a potential libido booster. Blueberries and blackberries contain compounds that are thought to relax blood vessels and improve circulation for a natural Viagra-like effect. They also fit conveniently in your partner’s belly button.
