i recently met a gay friend.we had a sexual encounter,he gave me a blowjob,i have no cuts on my penis and his mouth had no blood.lasted abut 30 secs. after that i placed my penis on his anus,i tried to push it in,2-3 times but i am not sure whether i penetrated him or not? maybe not,i wasnt topping and was doing it while laying behind hi.i also didnt cum near his anus,my penis-anus contact lasted for about 5-10 secs. after too weeks from the expoure i had a running nose which lasted 8-9 days,i had fever which lasted a week,back aches were also present for 3-4 days,headache was mild and lasted 5-6 hours.Fatique wasnt felt as i was able to play a football match during the intial few days of symptoms.Are these symptoms hiv ars related? should i test? also that frnd turned out to be hiv positive,he had his exposure(needle stick) an year ago.he has low viral load and high cd4 count although he isnt on any medications. whats the risk invoved?
