They wanted women.
Since real women could not go to them, scientists on Earth developed substitutes. Android females were developed, the surrogates, and shipped to the colonies. It was a violation of Earth's morals; but there were worse violations on the way if these weren't accepted.
For a while, everything seemed to be fine. It would probably have gone on that way, had everyone left well enough alone.
But the companies on Earth had the usual desire to improve their product. They called in sculptors and artists to dress up the appearance of the package. Engineers tinkered with the surrogates, re-wired them, built in subtler stimulus-response mechanisms, did strange things with conditioned reflexes. And the men of the settlements were very happy with the results.
