STI

STI stands for sexually transmitted infection. Sexually transmitted infections can also be called sexually transmitted diseases (STDs). STIs are spread through sexual behavior or contact. Some STIs can be transmitted through skin-to-skin contact or body fluids such as blood, pre-cum, semen, vaginal fluids or breast milk. STIs generally infect the genital area (penis, scrotum, vulva and vaginal opening), anus or mouth, although they can spread to other parts of the body if left untreated.
