I'm 31 and married now. Back in college, I dated this guy named Tim who I met through our network of sororities and fraternities. We lasted roughly 3 years. The year we broke up, I went with Tim to his family reunion at a beachside resort in California. His dad had reserved a bedroom for us with two single beds. We were asked to share one of the beds with his cousin, Daniel, who had down syndrome. I was bothered by this but I didn't want to intrude and I didn't want Daniel's parents to think I was discriminatory against his condition. Tim and I had just finished our finals and I had looked forward to the private time we were supposed to have at night after all the daily family activities. On our last night at the resort, Tim and I decided to mess around after Daniel fell asleep. In the middle of it, he woke up and stared at us, shocked. I tried to get off of Tim and run to the bathroom. That's when Tim held me down and begged me if I'd do him a favor. One thing led to another and I gave in to his request. I ended up having intercourse in between both of them. I felt so bad afterward I cried. I broke up with him the next day. But now I don't know why I am starting to fantasize about what happened back then? I hope to seek help soon. I want to be normal.
