Sexually Transmitted Infections (STI)

An "STI" is an infection that you can get while having anal, oral or vaginal sex.  You get these infections through the sharing of infected body fluids such as vaginal fluid, semen or blood. Some infections are spread through intimate contact, you don't even have to have sex. 
STIs can be bacterial or viral. Some are treatable and some are not.
