I had protected intercourse with a female CSW on DEC. 28. I have had several HIV tests including PCR, ELISA blood test, and oracheck -- all neg -- (last test was oracheck at 8 weeks), and docs and moderators have said I am at no risk for HIV. However, since a couple of weeks after the incident I have had a burning sensation in the tip of my penis -- sometimes extending to anus (especially after defecation) and also the burning gets worse usually after urination. All my tests so far for everything but HSV1 have come back negative, including a urine culture. I have had a round of Cipro 500 mgX2 a day for 7 days, a shot of azithromycine and 4 pills of azithromycine (one time treatment for chlamydia even though I was neg), and now I'm on Doxycycline 100 MG 2x a day (its been about a week in a 2 week course). I still have the burning, and I'm a bit freaked out. The sex was protected but I did touch her vagina and got fluids on my hand after which I masturbated with the same hand and she masturbated me as well. Has anyone ever gotten something like this through a similar experience, if so how was it resolved? I have also been having loose stool for the last month and loosing weight. Doc does not think it is herpes since I have not had any lesions and (tested neg for Herpes 2 4 weeks after incident -- i know it takes 3-4 months so haven't tested since) this has now lasted almost 6 weeks. If anyone has any advice or can add something -- PLEASE HELP!
