If you aren’t too hot when it comes to math (and keeping track of how many ladies you have bonked), then the Pocket Slutometer would do you a whole world of good.

There’s no room for romance in the numbers game. Points are scored every time you land a snog, a grope or a full-on shag. Hit the respective button and the built-in siren will announce news of your success to the world. The Pocket Slutometer: funny, flirty – the notch in the bedpost for the digital age!

Definitely not the gift to brag about when your girlfriend is around, you two-timing scum. The Pocket Slutometer can be pre-ordered for £6.99. Strange thing though – there is no reset button with this.
