About 2 months ago I was at a strip club. I received a lap dance. I did not have any oral or other sex. However during the lap dance the stripper put her hand in my pants and rubbed my penis for about 30 seconds and removed her hands. 

Welcome to the Forum.  I'll be glad to comment.  The exposure that you describe did not put you at any risk for STI.  There are no STIs that are transmitted by masturbation, whether you are the person performing or receiving the masturbation.  Your tests for gonorrhea and chlamydia prove that this is the case.  Similarly herpes and other STIs are not transmitted in this way.  It is not unusual for masturbation, particularly when a person is reaching onto another person's underwear, to lead to local friction and genital irritation but this typically becomes apparent a day or two after the event and heals quickly.  For this sort of irritation to last for two months is most unlikely. Further, if this were an STI, the symptoms would not come and go.

What you are experiencing may represent the heightened sensitivity that accompanies anxiety and increased vigilance for genital symptoms or it may be another, unrelated process but I am quite confident that it is not an STI acquired at the event you have mentioned.  There is no need for concern about STI, nor is there a need for additional testing related to your encounter in the strip club two moths ago. 

I hope these comments are helpful. EWH

Thanks. 

Urethritis is a general term used to describe irritation of the urethra (the tube in the penis that carries urine outside of the body).  Urethritis can be caused by a variety of things, including sexually transmitted infections and is diagnosed by demonstration of inflammation either from a urine specimen or from evaluation of a swab specimen taken from the penis.  As mentioned above, there is no reason to think that you have a sexually transmitted infection causing urethritis.  If you wish to evaluate this further, I suggest you see a urologist.  EWH
