What are the chances of contracting hiv. please answer i'm scared?

Depends on behavior: The chances of contracting HIV depends on which risk behavior you are engaging in. For example, if you are having protected sex and using condoms for intercourse (vaginal, anal, oral) or injecting drugs (but not sharing needles), then your risk is very low. But if you're having unprotected sex or sharing needles with someone who is HIV+, then your risk is much higher. Get tested if you're unsure.

Love safely: Your risk depends entirely on your behavior. If you have passive unprotected anal intercourse with a heavily-infected partner, it is highly probable that you will become HIV positive. If you forego sharing needles and use barrier protection so as not to exchange body fluids until you are in a monogamous relationship with an HIV-negative partner, you'll stay okay. Don't gamble beyond this.
