Hello, over a year ago so december 2016 I had unprotected oral sex with a man I'd known for a while, there was no cum/semen in my mouth, and we did not have sex. I have never had sex, we just made out after that. However, I feared I had contracted HIV however when I started to donate blood, in November 2017, my HIV test came out negative. My question is, I now have a warm feeling in mt feet and the internet is telling me it is HIV/AIDs and I am starting to get worried, even though I have had no sexual contact with anyone since then (I'm 18), however I could have diabetes since both my parents have it, which could be what's causing this. Is there any chance I have HIV ? the tests are negative after 1/2 years and I just need professional reassurance
