Do YOU know how many calories a night of sex burns? Try this sexercise calculator

This new sexercise calculator is sure to set a few tongues wagging

THERE seems to be a calculation for everything in the modern world - but this latest sex calculator could be the best thing ever.

Have you ever wondered how many calories a burning night of passion could expel? Look no further as there's a sexercise calculator on the market.
All it asks is your gender and weight, and your partner's gender and weight - then which position you've been in and for how long.
It breaks down into awe-inspiring detail how many calories you've burned and what other exercise you'd need to do to burn the equivalent.
For example, for a woman and man of average weight having sex in 'doggy style' for 20 minutes burns just 52 calories for the woman. 

That's the equivalent of 1.4 miles of cycling for the man and 1.2 miles for a woman - and 23 minutes of heavy lifting in the weights section.
In terms of food that's a whole hot dog - plus bun - for the man, and nearly a whole dog for a woman.
Or why not wash it down with nine Doritos?
The calculator is part of a service Superdrug is providing with their online doctor format - soon to be rolled out across their website for all and sundry to have a play with.
Swap the traditional post-coital cigarette for this snazzy calculator, and work out how much many calories you've burned.
