Apple founder Steve Jobs is hailed by many as a technological and pop culture innovator. But a new book by ex-girlfriend Chrisann Brennan exposes that Jobs was also great in bed, used the pull-out method as contraception, and engaged in the ancient practice of tantric sex.

In her book, titled The Bite in the Apple: A Memoir of My Life With Steve Jobs, Brennan reveals details of her five year relationship with Jobs in the 1970s. That relationship resulted in a daughter, Lisa, who Jobs denied before a paternity test in 1979 proved he was the girl’s father. After that he began paying $500 a month in child support.

It’s no surprise that Jobs fathered a child with Brennan. As she notes in the book, the only contraception the couple used was the pull-out method, which is typically considered one of the most ineffective ways of preventing pregnancy. “Our birth control method up to that point was Steve’s coitus interruptus, also called the pull-out method, which for him was about his conserving his energy for work.” Brennan also said that Jobs didn’t want to have an orgasm because he wanted to build “power and wealth by conserving one’s vital energies.”

One of the most interesting revelations is that their relationship hit a rocky patch when Jobs returned from a trip to India and “asked if [she] would make tantric love with him in his garden shed.” Tantric sex is a 500-year-old practice that involves connecting with one’s partner on both a physical and spiritual level. Though Brennan said she refused to engage in tantric sex because she and Jobs were not “spiritually prepared for the experience,” taking part in the ancient practice could have been beneficial to both of their health and mood — and could have even improved their spiritual intimacy.

"In the classical sexual ritual, the participants worship each other as embodiments of deities,” said Mark Michaels and Patricia Johnson, authors of Great Sex Made Simple: Tantric Tips to Deepen Intimacy and Heighten Pleasure. “We encourage people to bring an attitude of reverence into their lovemaking and to all their interactions. The tantric approach has far more to do with your mental approach than with technique. It's certainly got nothing to do with bragging about staying power."

Clinical psychologist Dr. Judy Kuriansky says that tantric practices, which originated in India and subsequently traveled to Nepal and China, are about using breath techniques to create energy between you and your partner. The tantra is intended to "expand your capacity to love." Tantric sex slows the sexual process, focusing on the pleasure of connection with both your physical and spiritual being and your partner's. Sessions have been known to last up to 8 hours.
