Sexually transmitted infections, or STIs are infections that can be caught, or passed on when you have sex, or when you have close sexual or bodily contact with another person.
You can find out more here about the different STIs, their signs and symptoms, and what to do if you think you may have one.
If you have any questions or worries, you can always contact Ask Brook. Ask Brook is confidential. That means we won’t tell anyone you’ve contacted us unless we think you are in really serious danger.
