4 years ago, a random guy offered me a lift ride.He was a gay and asked me to give him a blowjob but I was reluctant.Then he asked me to let him to touch my penis so that he would leave me.I was very young,afraid and allowed him to touch my penis.I am 21 now,very skinny,frequently get mouth ulcers,I have tinea and recently got sinusitis as well.One day I went through the symptoms of HIV and found similar to mine.I suspect that the guy applied some HIV infected blood on my penis tip.Can anyone get HIV in this manner?Please clarify.
