Welcome back to our Forum.  I happened to pick up your new question.  I have reviewed your earlier interaction with Dr. Handsfield and agree with all that he said.  From your post it is clear that your concerns about having acquired an STI from your unplanned exposure continues to worry you.  With this in mind, I agree with your decision to get tested, anticipating that the test will be negative and, hopefully, give you peace of mind.  I would recommend against testing for other STIs for all of the reasons Dr. Handsfield has already outlined.

As for the possible cold sore you may be experiencing, IF it is a cold sore, I am confident that it is not a consequence of the events 6 weeks ago which you have described.   My confidence comes from your statement that you did not kiss your partner and your mouth only contacted your partner's breasts.  Cold sores are caused by herpes simplex virus type-1 (HSV-1) and are most often caused by contact with an infected person's mouth (or, less commonly, from genital exposure).  I am not aware of any instances in which someone has acquired HSV-1 from contact with another, infected person's breasts.  Parenthetically I would also point out that the majority of American adults have HSV-1 even though the majority do not experience cold sores from their infections. The majority of these infections are acquired in childhood or the teenage years and most infected persons are not aware they have HSV-1.

Personally however, given the information you have provided, I am skeptical that your lip discomfort or the continuing, intermittent urinary symptoms you mention are in any way related to the events six weeks ago that you have described.  Rather I suspect (as Dr. Handsfield has already mentioned) that you have become hyper-aware of normal body sensations and are attributing them to this exposure.  My suggestion is that you get the testing you plan for gonorrhea and chlamydia, and then put your anxiety/guilt behind you.  EWH

Part of the reason Dr. Handsfield suggested you test only for gonorrhea and chlamydia is that these tests, in particular, are very sensitive and false positives, while they do occur, are quite rare.  Odds are that your tests will be negative.  When they are, believe the result.  On the other hand, asking to be tested for "everything and HSV in particular, is asking for a false positive test result.

As I wrote my reply to your original question, I found myself whether you mentioned your accidental exposure to your wife or not.  Now it is clear that you have not.  This strengthens my suspicion that a major contributor to your concerns is guilt/shame and suggests that having that all so difficult talk with her might be helpful to you (although I would mention the part about you kissing her breasts during your accidental exposure- hard to make that sound un-intended).  Perhaps telling her about the fact that your guilt has plagued you might help as well.    EWH
