Suggest Treatment For Genital Wart,rashes On Legs And Scalp

Hi Beloved Doctors, I need help. My name is Dave and I'm from Manila Philippines. I had sexual intercouse with 2 strangers 3 (same sex, insertive) years ago and a year ago respectively. With my first intercourse, I developed some form of genital warts around my anal area, however, over a few weeks, it just miraculously disappeared. I never had any medications. Currently, I also have some form of dermatitis, really itchy, flaky and pink rashes. I learned just this month from a friend that the person whom I had unprotected sex with 3 years ago came out that is hiv positive. Because of this, I went to a clinic who administers HIV testing. In 20 minutes, I got the result and it is non-reactive on both HIV1 and 2. Does this mean that I'm negative? Are the results of the rapid tests conclusive? I get paranoid with the genital warts and these rashes on my legs, ears and scalp. Please help. Need to know if I need to have further tests despite results are non-reactive. Thank you very much.
