Sexually transmitted infections (STIs)
If you're worried because you think you've got an STI, go for a check-up at a sexual health clinic as soon as you can.
Do not have sex, including oral sex, without using a condom until you've had a check-up.
You can have an STI without knowing it and infect your partner during sex.
The symptoms of an STI can include:
- an unusual discharge from the vagina, penis or anus
- pain when peeing
- lumps or skin growths around the genitals or bottom (anus)
- a rash
- unusual vaginal bleeding
- itchy genitals or anus
- blisters and sores around your genitals or anus
- warts around your genitals or anus
- warts in your mouth or throat, but this is very rare

Why you should go to a sexual health clinic
You can see a 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 the GP and you may not have to pay a prescription fee for treatment.
You can feel comfortable sharing information about your sexual activities or orientation with a doctor. You do not need to give your real name or tell staff who the GP is if you do not want to.
No information about your visit to the clinic will be shared with the 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.
What happens at a sexual health clinic
At a sexual health clinic, a doctor or nurse:
- will ask you some questions about your sex life
- may ask to look at your genitals or anus
- 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 do not want to do this, the clinic can usually do it for you without naming you.

- Genital warts
