Please please please help
A year and a half back I had unprotected oral sex with a prostitute.the biggest mistake of my life.a couple of days later I noticed swellings and redness in the meatus and I immediately went to a general physician and told him, he made me take a blood test and a urine test.the test results came back normal except there was slight pus in the urine from the urine test.the doctor prescribed certain antibiotics like azithral and also a cream to apply on the meatus.after the course of the antibiotics I went back and the doctor told me I’m cured and he didn’t even tell me what I had.the swellings in the meatus subsided and doesn’t appear anymore but my meatus looks different now from what it was before I had oral sex.there is a tremendous amount of guilt and anxiety ,I think about this and repent everyday.I want to get on with my life but this incident is holding me back even though it has been a year and a half now I’m not able to get over it.still at the back of my mind I feel I’m not cured and I have some std.I also don’t want my parents to find out.the only symptoms I had were the swellings,but now it’s gone and also rarely I experience a burning sensation when masturbating(when I come).I also heard sometimes STD don’t respond to antibiotics and this makes me even more anxious and worried.please help me out I would really really appreciate it!
