I don't think I'm some elite controller I think it's just a slow to possibly no increase rate in VL..
I think you deserve answers to your particular immune response. If the answers are available. If you are hoping to have no increase in VL, then that sounds kinda like an elite controller.
Also I think you should get an answer about your individual risk vis-a-vis barebacking without treatment. If you are indeed fortunate enough to not need treatment for some time, then it seems to me a doctor should tell you to your face what re-infection might mean specifically to you, since you are in unique situation..
In other words, if your doctor isn't interesting in answering these questions or offering expertise and informed opinion, why don't you try to find a specialist who will.
