It's going to be okay just kekp calm. GWs are horrifying, but unlike most other viruses, your body is capable of killing it off when you are young and healthy. Also, warts are a low risk HPV strain, which means that they do not give you cervical cancer. He could have unknowingly given you a high risk HPV strain, and you would have found out next year at your next pap, and it may have been too late and already started to form cancer cells.

Good Luck

Try to relax and then when the results come in, you can take it from there. You don't know if he cheated or not, so don't think too much of what he's said.
