Hello...my boyfriend and I broke up in May, in June he comes to my house and says he just came back from the doctor and tested positive for hpv and has warts. He says it had to have come from me as he hadn't slept with anyone but me in 7 yrs. We were together for almost two years. I do not have warts. I went to the doctor the next day and insisted he test me for every std known to man. I explained the situation and asked to please be tested for everything. All of my tests came back negative. Is it possible for him to have warts and not me? I know it takes time to show up, but if he has warts, does that mean I have it too, even though I tested negative for everything? He said that I could have tested negative but still have it. An undetectable strain? Please clear this up for me if possible. I am not sexually active now, but I would like to know. Could I still have hpv that causes warts and not know even after testing negative?
