It is not normal to bleed during or after sex, especially if you are not menstruating. It can be a sign of a Sexually Transmitted Infection (STI) or cervical cancer. Cancer can kill. STIs can cause serious illness or infertility if untreated. So go to a clinic IMMEDIATELY. ALL sex partners must be treated or you will be infected again. Use condoms to prevent STIs and HIV.
