Recently I had gone to a massage parlour. I don't know what got into me , she removed the clothes and I fingered her and there was a brief episode of cunnilingus. HIV , I Believe is not a great risk. But what about other STDs like Gonorrhoea chlamydia? our private parts might have brushed during the process (I am not sure). I had a burning sensation while urinating a couple of days after , though it was because of the drinking and dehydration , it went away as soon as i drank a lot of water. Then again, the burning sensation came back in another 4 weeks, that too after a night of a lot of drinks. That too went away in an hour as i drank a lot of water. Could these be symptoms of an STD? Please help.
