If you feel that your relationship is turning from deeply-in-love to boring, it isn't because you want to make it dull.

The reason is that you simply find yourself in no mood for romance. Grab these foods to spice up your relationship and sex life.

The reasons for a lacking libido can range from too many things on your to-do list and working too many hours to your hormones being out of whack. This is where food plays a role.

Here are four delicious items you can work into your diet that will increase your libido, and help you work out of your clothes...

1. Watermelon
Coined 'the new Viagra', watermelon contains citrulline, an amino acid that relaxes blood vessels thereby increasing your sex drive.

2. Aparagus
Asparagus is high in the B vitamin folate that helps increase your production of histamine. Histamine is important for increasing the sex drive in men and women.

3. Avocados
Loaded with potassium, avocados boost libido for both sexes. And they're rich in folic acid that provides energy and stamina - both of which are important once your libido is restored.

4. Chillies
If you like it hot and spicy, this one will bring a smile on your face! Chillies contain capsaicin, a chemical which also increases blood flow and triggers the release of mood-enhancing endorphins that naturally pump up your libido.
