Hi, I had protected veginal sex and unprotected oral sex 18 months ago. These 18months i do not have any symptoms, happily living normal life. Recently started urethra burning and scant clear liquid discharge. I have gone through, HIV, HbSAg, HCV, HSV (IgG and IgM), chlamaydia (IgG), syphils and VDRL blood tests. Also, urine multiplex PCR for chlamaydia, gonorrhea, micoplasma genitalim, Trichmoniasis, ureaplasma, and 5more bactrial. All tests negative. I am worrying a lot, is there any connection between my 18 months old incident and current symptoms? I need to join in new job, can't able to focus on anything.
