Work out how many people you’ve indirectly slept with

Does hand stuff count?


How worried are you about having an STI? Well there’s now an online calculator to work out just how likely it is.

The Sexual Exposure Calculator, crafted by online health service Dr Felix, works out how many people you have indirectly slept with based on the average number of sexual partners your own sexual partners have had.

The calculator can also work out how likely you are to have each type of STI, which is just as horrible as it sounds.
