Dear sir/madam on 20 Aug 2018 a boy sucked my penis for about 10-15 minutes. I neither sucked his penis nor fucked his anus. I have checked his mouth immediately after this there are no sores, ulcers,cuts, openings,bleeding gums in his mouth. I don't have any cuts, openings,ulcers, sores on my penis. Now my questions are 1} Does hiv and other STDs transmits in my case. 2} I got urinary infection recently (it cured now) is this because of that blowjob. I am not sure about his hiv status and he is a stranger to me and he is not commercial sex worker.
