Sexually transmitted infections (STI).

An STI is an infection that can be passed from one person to another, usually through sexual contact such as unprotected vaginal, anal or oral sex, by genital contact and through sharing sex toys. Sometimes these infections can be transmitted in ways other than sex, for example - during pregnancy or childbirth, or through blood transfusions or shared needles. It is possible to contract an STI and be unaware, as STIs don't always cause symptoms. That’s why regular testing and practising safe sex is super important, to make sure you’re keeping yourself and your sexual partners safe from any potential infections.

There is a lot of stigma and embarrassment surrounding STIs, but it’s important not to let that stop you from taking responsibility for your sexual health. Having an STI doesn’t mean that you’ve done anything wrong, or that you are unhygienic or dirty- they are very common, and usually very treatable.
