As a 9 year old, Baltierra says he was molested by a friend of his older sister. "One day I went over to her house with my sister and some other people, and for some reason or another, everyone else left but this older girl and me," he recalls in the book, out March 3. "For the next several hours, it was sex act after sex act after sex act. It went on all day. She had us going everything she could think of, one thing after another." He says he felt confused: "I didn't know what the hell had happened."

Baltierra says he was deeply affected by the scary events that took place that day. "It made me think sex was something kids could do, which influenced me to act too sexual when I was too young." He admits he broke up with his elementary school girlfriends because they were "prudes." "We were 10-year-olds!" he writes. "It's so messed up."

Before he met Lowell in 7th grade, he was already sexually active. "I wound up finding a girlfriend who wanted to do it all the time," Baltierra says. "She was crazy, and that was basically all we did."

Though they would go on to have a long-lasting love affair, Baltierra had only one thing in mind when he met Lowell for the very first time at age 12. "She's got bigger tits than any other girl in the 7th grade," he thought when he saw her in music class.
