Doctor,
I recently met and am dating a woman who disclosed to me that her prior boyfriend had herpes. She was sexually active with him for 3-4 months (the duration of their relationship). She said that he was on medication and they used protection, and that she has tested negative (although I don't know what test she took). Also, I have not asked her, but I assume she did not use protection for oral sex with him.
We are not sexually active, except I receive oral sex from her.
I would like to know how/if I can protect myself in this situation. She parted ways with her ex-boyfriend about a month ago, so I would guess that it was been around a month since her last potential exposure. What can we do to determine if she is really herpes-free? If she does have herpes, would she become symptomatic sometime in the next couple months (in which case we can "wait and see")? If that approach is not viable (i.e. if she can be positive but not symptomatic), what type of test/tests can she take that would yield the most accurate results (again, assuming she shows no symptoms)? Thank you.
