I dont have unprotected sex or inject needles, what's the risk of getting hiv? like from outside the body in the environment, is there any other way?

No risk, no worries: HIV is not transmitted by contact with the virus or infected blood or body fluids in the environment. The virus is fragile and dies quickly outside the body, and large amounts of it must have contact with susceptible cells deep inside the body. Choose your sex partners wisely, use condoms for new or potentially unsafe partners, and never share drug injection equipment, and you'll never get HIV.
