I also once told my husband that I had rape fantasies. I was truly amazed what kind of fantasies he had and was ashamed/afraid to tell me. He said that he fantasised about having me screwed up at work, and then telling about that to 3 or 4 of his friends. They would blackmail me. Since I would never have met them before, and would have thought that I could go to jail, I would be made to do *absolutely* everything they wanted. And they would return for more, pushing my limits further every time. At first it would be only about taking turns on me, "having" me in all my orifices. Then they'd do double- and tripple-penetrations of me. And finally they'd start sexually torturing me... fisting, maybe later even double-fisting me... All this time they would videotape our "sessions" and they'd send the videotapes to my husband, secretly from me. And he would know everything, every little detail, but I wouldn't even suspect that he knows about my blackmail... until he started asking questions, and I slowly would have to confess...
And it was just one of his fantasies that he told me after I confessed in my rape fantasies... It might really be interesting how inhibited we are to make a first step, and what kind of fantasies live in each of us...
