We are very open and honest to each other and he recently admitted to having dirty thoughts about his relatives (aunts, cousins and even his sister!!!!) and to my friends...OUR friends. He used to masturbate to them even during the span of our relationship..he said he's going to change now that we've confronted it but he gets these thoughts involuntarily still....and he keeps remembering other girls he fantasized about...And this is very upsetting and I do not know what to do!
