I had sex outside my marriage in December. Afterwards, I had protected sex (with a condom) with my wife three times. I had no symptoms of any STD. However, out of anxiety I did a full STD check and was tested positive for gonnorhea. I was then treated for it. What are the chances that I could have given it to my wife, even with the use of a condom? And do I need to tell her about this?
