Doctor, I have been dealing with the thoughts of having HIV for a year now. One year ago I was given oral sex by a sex worker, while receiving I masturbated the sex worker for about 30 seconds. When I was finished I drove home which was about 10-15 min away. When I got home I had sex with my wife and masturbated her. After this occasion happened a day or two later I noticed a rash on my finger that I used for masturbation. I then a few days later started to get stressed out of my mind and formed a sore throat and it seemed to last a long time. In the past year I have been tested 3 weeks after the occasion, 6 months after and 12 months after. All tests were negative. My wife, I have noticed has broken out in cold sores 2-3 times in the last year and I have had canker sores for what I believe more than I have ever had before in my life. While being tested for HIV, I was also tested for any other STD's. Is it possible that I infected my wife with my finger on the night of the occurrence 15 min later? While every time I have gone to the center they tell me that I am crazy, that you cannot get HIV from what I did and if it were possible it cannot live outside the body for me to drive home and then give masturbation 15 min later, and because I have been tested 5 times and all were negative that I need to seek psychological help I am still stressed that my one time affair may have ruined my life. Does my wife need to be tested if I have been tested as many times as I have, and believe that if anything is wrong it would have to do with that night? It just seems that their are too many ironic things that are happening to my wife and I that are still causing me to think of the possibilities of HIV. I could also be driving myself crazy by reading every post and watching every little thing wrong with me and my wife.
