The cities where you have the best chance of catching an STD have been revealed – and it's bad news if you live in Cardiff or Glasgow.
The capital of Wales was named the worst city in the UK for sexual health just before the Scottish city.
2,368 Britons from 28 cities were asked about nine aspects of their sexual health.
11 percent of the people in Cardiff said they would not get an STD test after unprotected sex, while only 22 percent are wearing condoms.
The city also had the largest number of people who said they would not recognize the symptoms of an STD.
76 percent of the people interviewed in Edinburgh had never had an STD check, the highest on the list.
On the other hand, Bristol had the lowest number of people who have never been tested for an STD with 42 percent.
Only 17 percent of the Bristolians would wait until they had seen the symptoms to be checked.

The study, conducted by Medicine Direct, also showed that 32 percent of Britons do not receive STD checks because they do not believe they are at risk for STDs.
33 percent of adults said they were never taught about sexually transmitted infections in school.
Superintendent Pharmacist at Medicine Direct Hussain Abdeh said: "Our research has shown that people take a risk with their own health and that of others.
"Considering how easy it is to get your sexual health checked these days – whether through post-tests, sexual health clinics or your doctor – there is a real need for improvement within our sexually active population.
"It is worth remembering that some STDs, such as chlamydia, cannot have visible symptoms, but can be very harmful if they are not treated."
