- Bryan Johnson says he's trying to fill gaps in his young adult son's sex education.
- "We, of course, have the basics covered, but his only source of education has been porn," he said.
- Johnson said he wrote a sex "instruction manual" after realizing there were gaps in how people learn about intimacy.
Bryan Johnson says he didn't teach his son enough about sex and wants to change that.
"He is 20 now, and we were talking about sex. He had these questions, and I was like, 'I've never educated my son on sex,'" Johnson, the tech entrepreneur known for his pursuit of longevity, told executive editor Zak Jason at Business Insider's The Long Play event on Tuesday.
"We, of course, have the basics covered, but his only source of education has been porn," he said, adding that there's an "entire generation of people who have not been educated" on how to make love.
That realization led him to try to explain intimacy more deliberately. "What I wrote was basically an instruction manual on how to have sex," he said.
Although people have called it a "'50 Shades of Grey' longevity version," Johnson said it was really "like 10 lessons" he was trying to get across.
One of those lessons, he said, is the difference in arousal between men and women, which can create a mismatch if partners move at different speeds.
"Basic stuff like that, so it was like trying to educate people on, how do you create good relationships in a loving manner," Johnson said.
He added that his son has largely taken his openness in stride: "My son is so cool."
Johnson, who says he spends about $2 million a year on efforts to reverse his biological age, has long been public about sex as a key part of his broader approach to health and longevity. He previously said that he wears a small device on his penis to measure his nighttime erections.
At Tuesday's event, Johnson said founders in "monk mode" may be missing the role relationships play in performance.
"Sometimes it takes a bit for them to realize that, but a good partnership is really beneficial for mental health and physical health," he said.
