William Shatner desperately tried to avoid romancing obsessed Star Trek fans - because they wanted to enact their sci-fi fantasies with the actor.
The 77-year-old, who shot to fame as Captain Kirk in the original 1960s TV show, insists he couldn't enjoy flings with the series' most devoted followers because he was so turned off by their bizarre bedroom behaviour.
In his new autobiography, Up Till Now, Shatner explains how women would pretend they were being "beamed up" by the Starship Enterprise commander, shrieking: "So, this is what it's like to be in bed with Captain Kirk!"
He writes: "You can't imagine how much of a downer that is in every sense of the word."
