You sound young. Your questions also imply that you are pretty clueless about HIV transmission. You need to get better educated on how HIV is transmitted. Your health is your responsibility. Knowledge is power. As far as sex is concerned, what you don't know, can hurt you. Sex lasts for minutes and HIV lasts for a lifetime.
As a sexually active person, you should know that you should always be using condoms for anal/vaginal intecourse until you are in a mutually monnogamous relationship with someone who is conclusively negative. Do this and you will likely avoid HIV infection. Fail to do so, and you may not avoid it. Also, as a sexually active person you should be getting an annual STD/HIV screening. It's the responsible thing to do.
You never had a risk my friend
