Steve Jobs' first girlfriend from their sweet teenager years until their 20s, Chrisann Brennan, came out with a memoir titled The Bite in the Apple: A Memoir of my Life with Steve Jobs, to be available on Oct 29.

Brennan is the mother of Jobs' first child.

The memoir revealed the quirky, amusing and peculiar side of Jobs that it stirred controversy as early as now.

In the memoir, Brennan revealed that 15 years after they broke-up, Jobs surprisingly called her to thank her for the most shocking reason - the amazing sex they had when they were younger and still together.

"He was married at the time of his call and all I could think of was, Whoa . . . men . . . are . . . really . . . different. Imagine if I had called him to say such a thing," Brennan said.

Jobs was already married to Laurene Powell in 1991 and had three children with her.

Brennan wrote that her relationship with Jobs ended in 1977. She was 23 at that time and was pregnant with a child. Jobs had sadly denied being the father of the child even with a paternity test proving he was the father.

But later, Jobs accepted her daughter to Brennan and sent her to Harvard.

Brennan remembered vividly how Jobs loved the 1940s and in fact was convinced that he was from that era.

"Steve often said that he had a strong sense of having had a past life as a World War II pilot. He'd tell me how, when driving, he felt a strong impulse to pull the steering wheel back as if for takeoff. It was a curious thing for him to say, but he did have that sense of unadorned glamour from the forties. He loved the big band sound of Tommy Dorsey, Benny Goodman, and Count Basie. At the first Apple party he even danced like he was from the forties," Brennan wrote in her memoir.

Brennan claimed that after Apple's success, Jobs had become "full of his own self-importance". He refused to do the dishes and was nasty to staff in restaurants.

"Steve would order the same meal night after night, yet he'd complain bitterly each evening about the little side sauces that were served with it, cutting the air with disdain for the wait staff who would serve up such greasy-salty-tasteless-mock-fine cuisine. Steve would run down the waitstaff like a demon, detailing the finer points of good service, which included the notion that 'they should be seen only when he needed them.' Steve was uncontrollably critical."

As for the sex, Brennan agreed that their lovemaking was magnificent.

"We remembered different things. Mainly I recalled how awful he was becoming and how I was starting to flounder. But he was right: our lovemaking had been sublime. At the time of Steve's phone call, I found that as I listened I was as awed by the memory as by his strange need to risk an expression of such intimacy. After I hung up I stood still and thought, maybe Steve thinks that love has its own laws and imperative. But why call now?"
