What are the symptoms of STIs?
STI symptoms vary from obvious itchiness, soreness, rashes or redness, to pain when passing urine, discharge from the penis or vagina, and lumps or sores on the genitals. Some symptoms may also be internal - for example, pain inside your stomach or groin.
Sometimes you will get no symptoms at all or the symptoms will take a long time to show. This means you could be passing infections on to other people without knowing it.
The only way to know you have an infection is to have an STI test.
