Yellow fluid from the penis which is not urine is NOT normal-this can be a sign of a Sexually Transmitted Infection. White/slightly yellow discharge from the vagina is normal. If it is very yellow or the amount/colour changes drastically this could be a sign of an infection or Sexually Transmitted Infection (STI). If you have this, go to clinic IMMEDIATELY-untreated STIs can cause serious illness and infertility. ALL sex partners must be treated or you will get infected again. Use condoms to reduce the risk of STIs and HIV.
