Sexually Transmitted Infections (STIs) | Causes & Risk Factors


Am I at risk for having an STI?

If you've ever had sex, you may be at risk for having an STI. Your risk is higher if you have had many sex partners, have had sex with someone who has had many partners or have had sex without using condoms.
