He wanted tantric sex in the garden shed, but didn't want to climax.
The reason: He wanted to conserve his energy for work.
The bizarre sex life of Apple founder Steve Jobs, who died in 2011, aged 56, has been detailed in a book by ex-girlfriend Chrisann Brennan.
The book, scheduled for release at the end of the month, is called The Bite in the Apple: A Memoir of My Life With Steve Jobs.
Ms Brennan wrote that Mr Jobs asked for tantric sex after returning from a trip to India, Mail Online reported.
She said that they "shared nights of lovemaking so profound that, astonishingly, some 15 years later, he called me out of the blue to thank me".
Ms Brennan dated Mr Jobs for five years until she became pregnant at 23 with their daughter, Lisa.
They began dating in 1972. Two years later, he returned from India a changed man.
He had come across a religious gathering, shaved his head and experimented with drugs, she wrote.
Mr Jobs then returned to the US, leaving all his money to his travel companion.
After he returned, "it all broke open between us when he asked if I would make tantric love with him in his garden shed", she writes. She said she refused because they weren't spiritually prepared for it.
When Ms Brennan told him that she was pregnant, "Steve's face turned ugly. He gave me a fiery look. Then he rushed out of the house without a word."
Mr Jobs denied that the child was his, but a paternity test in 1979 proved that Lisa was his daughter.
He accepted Lisa and paid for her to attend Harvard University. She is now a journalist.
In 1983, he told Time magazine that "28 per cent of the male population in the United States could be the father".
