FDA funded research at the University of Texas show that watermelon can boost libido.

It turns out that this delicious and watery fruit contains citrulline amino acid.

Citrulline is beneficial to our cardiovascular system and also helps relax the blood vessels and increase sex drive.

In fact, watermelon influences our body the way well-know Viagra does, but without adverse effects.

Note: Eating 6 slices of watermelon is enough to boost your sex drive. It should bring the same effect you get after taking one Viagra pill.
