Sexually transmitted diseases (STDs) usually haunt the nether regions, whether germs have set up shop in the urethra, clustered around the cervix, or burrowed inside a cell. There, they might cause symptoms, like a burning sensation when urinating, unusual discharge, or warts or sores in the genital area.
Sometimes, however, STDs can infect other parts of your body, usually places that boast environments that are warm and moist, just like your genitals. For example, the virus that causes genital warts can also infect the throat to cause growths inside the airway. Oral sex can transfer the bacteria that cause gonorrhea from a urethra to a throat. And herpes can spring up around the mouth or in the genital region, and can be transferred between the two locations.
