STIs

Sexually Transmitted Infections

There are many different types of sexually transmitted infections. They are mostly passed from person to person through bodily fluids, like semen, vaginal fluid, or blood, or just by skin-to-skin contact in the genital area. Most STIs can be treated, but not all can be cured. If you have had unprotected sex, there is a risk that you could have an STI, and if so you could pass this STI on to someone else.
