STI and HIV Risk Calculator

  • Risk is not an absolute nor is it a certainty, especially for women having sex with women. Rather, risk is seen as an estimate for potential danger of future damage or the relative probability of a generally negative outcome based on current behaviour. As such, levels of risk may vary from one person to the next.
  • Are you unsure of what your current level of STI or HIV related risks are?
  • Are you perhaps concerned about past situations that may have involved some risk?
  • Do you sometimes convince yourself that you are being safe, while at the back of your mind you know that you have taken a number of risks?

Well then this easy-to-use risk calculator is for you. Answer each of the following questions by selecting the most appropriate option.


This risk calculator is not meant to give you a definitive risk assessment but is rather a rough guide to help you assess your current and recent practices.
