I want to have sex with my husband that betrayed me and we have had sex many times before. But there have been a few times that everything is going great and all of the sudden the affair partner comes to my mind and it’s just difficult to continue pretending that I'm enjoying it. I had stopped or even closed my eyes, because I could not look at him but I did not want to be rude to stop in the middle. This makes me wonder when and how am I going to get thru this. What should I do when this happens?? Thanks
