If you have had sex without using a condom with someone who has an infection, you could get an infection, even if your partner has no symptoms. Don’t wait for symptoms to appear.
If you think you’ve been at risk, ask for a check-up at your GP’s or at an NHS sexual health clinic, often called an STD (sexually transmitted disease), or GUM (genito-urinary medicine) clinic.
NHS sexual health (GUM) clinics offer free checks and treatment for sexually transmitted infections. Some offer women-only sessions. The service is strictly confidential.
