If you have sex — oral, anal or vaginal intercourse and genital touching — you can get an STD, also called a sexually transmitted infection (STI). Straight or gay, married or single, you’re vulnerable to STIs and STI symptoms. Thinking or hoping your partner doesn’t have an STI is no protection — you need to know for sure. And although condoms are highly effective for reducing transmission of some STDs, no method is foolproof.
STI symptoms aren’t always obvious. If you think you have STI symptoms or have been exposed to an STI, see a doctor. Some STIs are easy to treat and cure; others require more-complicated treatment to manage them.
It’s essential to be evaluated, and — if diagnosed with an STI — get treated. It’s also essential to inform your partner or partners so that they can be evaluated and treated.
If untreated, STIs can increase your risk of acquiring another STI such as HIV. This happens because an STI can stimulate an immune response in the genital area or cause sores, either of which might raise the risk of HIV transmission. Some untreated STIs can also lead to infertility.
