I have been in monogamous heterosexual relationship with a woman for the past 4.5 years.  About 4 years ago I had an outbreak of blisters on my genitals.  I went to a local std clinic and they scraped the affected area.  The doctor said it was herpes, but did not tell me whether it was HSV-1 or HSV-2.  Since the initial outbreak, I have not had another outbreak.  Since the diagnosis at the clinic, I have had two blood tests for stds with my primary care physician (the most recent test was 1 year ago).  Both have come back negative for all stds. What is the likelihood that I have herpes?  If I do have herpes, is it safe to say that I have HSV-1, because I have not had another outbreak in the past 4 years?  My wife has not shown symptoms for either.  As a side note, she was diagnosed with shingles as a teenager.  It's my understanding that this would be completely unrelated to my initial diagnosis.  Please advise.  Thank you.
