Beam me up to Tantric Sex, so say the women who slept with space lothario William Shatner.

Shatner told the New York Post Page Six that many women who bedded him often had out-of-this world fantasies  with the Star Trek thesp.

"So this is what it's like to have sex with Captain Kirk!" Shatner giggled. 

"You can't imagine how much of a downer that was in every sense of the word."

Shatner, whose tell-all autobiography hits shelves, is enjoying success on Boston Legal.  The book also claims he was unaware of Trek costars disdain for him.

No word on whether Shatner, like Kirk, enjoyed his ladies green.
