The amount of people you’ve had sexual contact with with could be a lot higher than you think.
A new online tool reveals the amount of people you’ve “indirectly had sex with”, then calculates your STI risk.
The tool, created by online doctor service Dr Felix, follows on from a similar tool created by the company Dr Ed.
Both tools are based on the theory of the six degrees of separation – the idea that everyone is six or fewer steps away from any other person in the world.
For example, if you and your current partner have each had nine partners (the UK average), then you have supposedly been sexually exposed to 597,870 people.
That’s the entire population of Belfast.
According to the Dr Felix tool, these figures would give you a 6.11% chance of catching chlamydia and a 10.33% chance of contracting gonorrhoea.
“We carried out extensive research to gather accurate statistics for four of the most common sexually transmitted infections, chlamydia, gonorrhoea, syphilis and tichomoniasis alongside other common STDs like the herpes virus, human papilloma virus (HPV), HIV and hepatitis B,” the Dr Felix website reads.
