After one night of heavy drinking my body had gained rashes in my arms, legs and in the chest area. They are red and not itchy. I m worried that this might be an HIV rash because a week before that drinking incident I gave a blowjob to a man I met online. The blowjob only lasted about 15 seconds because as soon as I tasted something salty (might be precum) I immediately stopped. An hour before the BJ I brushed my teeth and we ate dinner. I m already paranoid even if he has already reassured me that he regularly gets tests and he is in the clear. Am I at risk at getting HIV? Currently it has been 10 days since the BJ incident and still I m feeling ok except for the rashes.
