If you're worried you have got an STI, go for a check-up at a sexual health clinic as soon as you can.
Don't have sex, including oral sex, without a condom until you have had a check-up.
You can have an STI without knowing it and infect your partner during sex.
Many STIs have no symptoms at all, like HIV. The only way to know for sure is to get tested.
You can see your GP, but they'll probably refer you to a sexual health clinic if they think you may have an STI.
Sexual health clinics treat problems with the genitals and urine system. You can usually turn up without an appointment.
You'll often get test results quicker than from your GP and you won't have to pay a prescription fee for treatment.
You don't need to give your real name or tell staff who your GP is if you don't want to.
No information about your visit to the clinic will be shared with your GP or anyone else outside the clinic unless you ask for it to be.
You can ask to see a female or male doctor or nurse if you wish.
A doctor or nurse will ask you some questions about your sex life. They may ask to take a look at your genitals or anus and will tell you what tests they think you need
Some clinics offer home testing kits for some STIs.
If tests show you have an STI, you should tell your sexual partner and any ex-partners so they can get tested and treated as well.
If you don't want to do this, the clinic can usually do it for you without naming you
