I have found that my fantasies don't come close to reality. What about your experience? Example when I was driving my route I had time to fantasize and I always thought if I could have sex with this special person I would do many things. What really happened is I finally got to have sex with this person I dreamed of and I was so excited that I came right away and lost interest in going on. In my mind he helped me go on but in real life he lost interest after he came too.
