After exploring the power of peanuts (njugu) and chocolates, now the focus shifts to watermelon in a series of foods that enhance men's sexual stamina.

It is easy to rubbish watermelon, but it is not easy going into a bedroom match without taking a watermelon.

So what impact does this big and 'ugly' fruit have on men endurance in bed?

Watermelon makes a man's erection harder due to its richness in citrulline nutrient. This nutrient triggers the generation of nitric oxide which opens up blood vessels in the penis.

The effect is like that of Viagra because blood rushes into the vessels and a man achieves a hard erection.

It doesn't matter how you take your melon, you can eat the melon as it is or make juice.

Whatever makes you happy to make her happy.
