Ten reasons to have top sex

It found that men who make love once a week have twice the risk of erectile dysfunction compared to those who indulge in steamy sessions three times a week.

But that's not the only reason to have a good session. Here are some more good reasons to romp, as stated by The Sun.

Lose weight: Forget sweating it out at the gym - sex works every muscle group in the body, is great cardio-vascular exercise and will help you burn 300 calories an hour.

Stress relief: Getting horizontal can help banish the burdens of a hard day by increasing levels of the cuddle chemical oxytocin, which helps stimulate feelings of warmth and relaxation.

Enhance performance: Female athletes who had sex the night before an event performed better the next day, according to a study by the Norwegian University of Sport.

Scientists claimed the women felt more self-confident and relaxed than usual.

Sex keeps you looking and feeling younger, and helps lead to shiny hair and a glowing complexion thanks to the increased output of oestrogen and other hormones.

Pain Relief: Got a headache?

Forget the painkillers and indulge in some nookie instead as the feel-good endorphins released during sex can help alleviate aches and pains.

Fight Depression: The same pleasure and well being hormones can also relieve depression and anxiety.

Immune Booster: Having sex twice a week can ward off colds and flu, according to a study in New Scientist.

This is because it boosts lgA - the immune system's first line of defence.

Toning Wobbly Bits: Work on hard to reach areas such as tums and inner thighs with a few vigorous sessions a a week. It will help whittle you into shape in no time.

Live Longer: Men and women who bonk three times a week can halve their risk of suffering a major heart attack or stroke, according to a University of Bristol study.
