I have the opposite problem. My husband has fantasies of father daughter sex, involving our daughter (we have no children). These fantasies were involved in almost all sex play for four years. When we got married, he started talking about really having children, and talked about it as if he really wanted to act on the fantasies. He said his biggest fantasy has always been that he find a woman who loves him enough to give him her daughter. Since getting married, having children has become a possible reality and has me frightened. I took him to therapy with specialists who specialize in sex offenders and they believe he would act on his fantasies, if he hasn't already. They're most concerned with the detail he's put into his fantasies, making the daughter believe the sexual contact was her idea, how she'll feel so loved for being involved in such a relationship, how we wouldn't be able to send her to stay overnight with grandparents because she might tell, etc. He insists these are just fantasies and "dirty talk" but up until I took him to therapy his comments were, "I would never do anything if it weren't okay with you" not just "I would never do anything." The specialists are going to propose treatment and I feel that I may need to leave him if he refuses to participate. What do you think?
