Oh, all of it can be terribly confusing, lol!
OK, I'll hit what I can here. Did you get a type-specific IgG blood test? Do you have a copy of your results and could you post your actual numeric results here?
Since your results said you are only positive for Type II, I can think of three scenarios.
1. Yes, maybe you acquired Type II genitally and orally. I think that would be fairly unlikely, but it's possible.
2. The IgG test misses 10% of Type I infections, so maybe you are positive for Type I orally and the test just didn't catch it.
3. If your b/f has a history of fever blisters aka cold sores, then it's possible you had a pre-existing HSV-II infection, but just acquired Type I from him and that's why it didn't show up on your test results. That would also be fairly unlikely b/c having Type II does offer some protection from subsequently acquiring Type I.
Here's what I think might be useful. Post your test results. If you get oral symptoms again, go to the doc within 24-48 hours to get a culture or PCR swab done and typed and then you'll know what it is. Try to get your b/f to get his results. Typically if you just ask to be tested for STDs they WILL NOT test you for Herpes. But if he specifically asks if he has Herpes, I sure as Hell hope they're not telling him he does not if they haven't even done a blood test. Besides, if they did the type-specific IgG blood test on him, at the least is should show positive b/c he knows he has had cold sores in the past.
A first outbreak can last several weeks. Did they give you antiviral meds to control your symptoms? I don't think they can really know if this is your "primary" outbreak or a subsequent outbreak. That stuff is a bit confusing. The classic presentation would be a fairly severe OB shortly after acquiring the virus b/c your body would have no antibody response. But we certainly know many people don't even know they have H b/c they don't notice symptoms. And while a first OB is usually the worst and longest, some people will occasionally have a doozy of an OB later on in the game.
Oh, and if you did have oral HSV-II, I think it could certainly appear as a blister.
I hope that helps a little bit.
