There are a range of bugs and viruses that you can catch during sex. Learn about Sexually Transmitted Infections (STIs), how to prevent them, how to diagnose them and how they are treated.

Mycoplasma Genitalium

What is it?

Mycoplasma genitalium (MG) is a bacterial infection which can affect the opening of your cock (urethra), arse, vagina or front-hole.

How do you get it?

You can only get MG from sexual contact with someone who has MG — through condomless anal, vaginal or front-hole sex.

What are the symptoms?

Most people don’t have symptoms when they get MG, which means you can have MG and not know about it.

Common symptoms may include:

  • Pain when pissing
  • A discharge from your cock, vagina or front-hole
  • Irregular bleeding from your vagina or front-hole
  • An itchy arse
Diagnosis and treatment

A doctor diagnoses MG by taking a swab of your cock, arse, vagina or front-hole and a urine sample. Testing is only recommended if you have ongoing symptoms.

Treatment typically involves a short course of antibiotics with follow-up testing three weeks after completion to make sure the infection has cleared. In complex cases, your doctor may discuss alternative treatment options. Avoid all sexual contact until advised by your doctor to stop MG from spreading.

How do you prevent it?

Apart from not having sex, the most effective way to prevent MG is to use condoms during sex. However, MG can still spread even when these barriers are used.
