 [ Symptoms ] why would a girl age 13 knee keep dislocating it has happen 3 time in a year [ Disease ] in my opinion everyone should know their hiv status whether you have only had one partner or many partners the safest bet is to get a simple hiv blood test so you know for sure you are hiv free the reason i say this is because hiv is not spread only through sex other risky behaviors such as sharing needles to inject illicit drugs can spread hiv so can getting a tattoo or piercing with a dirty needle so do not be ashamed to get an hiv test then you will know for sure and set your mind at ease take care
