that's a relief. thank you. :)
If you have not had visible warts for over 6 months, the doctors on the Doctor's Forum believe that you are no longer infectious. They also believe that one day you could be infectious but they have no idea when this one day would be. So yes, you can impregnate your GF. Once pregnant, you may want to avoid unsafe sex with her to be sure she isn't infected while pregnant. However, do understand that condoms don't offer much protection and it is possible she already has what you have. The only way to tell is for her to get tested now.
so it is safe to have unprotected sex then on?
No test for men exists. If its been years since you had warts, you are probably not infectious.
