Did you actually look at the lab results from the LEEP with your doctor? Dis your doctor say you have mild dysplasia in the margins? Or do you actually still have CIN II or CIN III in those margins? If your doctor is not being clear, I strongly recommend a different doctor and a new biopsy before you let anyone carve you up, again. You need to be absolutely clear about what exactly is happening. I'm concerned about another LEEP not being necessary at this stage or, worse still, that the first LEEP procedure missed something altogether.
Once your boyfriend and you are infected, you can't give reinfect each other with the same virus. You could ge infected with a different strain, but not the same strain.
