I don't know if this will help, but you might consider getting a second opinion, and maybe with a progressive doctor who can actually answer these questions. You might have to pay out of pocket, depending on your insurance (and where you live), but is there a local Planned Parenthood? They may be able to do the testing, or refer you to someone, or help with education.
I do know that the virus can eventually pass out of your system, within two years. Also, 50% of sexually active adults get it at one time or another. Please don't let it make you feel icky. The fact that you are aware of it, and communicating this to your partners, puts you way ahead of most people carrying it.
