Sexually transmitted infections (STIs) are very common. They are passed on through vaginal, anal and oral sex with someone who has an infection.

The best way to avoid catching a sexually transmitted infection is to use a condom every time you have sex. Even if you're using other kinds of contraception to prevent pregnancy, like the pill or the injection you should still use a condom as well.
