ATLANTA, Georgia (CNN) -- Tyler Perry has, for the first time, revealed graphic details about the sexual, physical and emotional abuse he says he suffered as a child. 

"I'm tired of holding this in," Tyler Perry wrote on his Web site, "... so I've decided to give some away." 

Perry recounts in a message posted on his Web site and in an e-mail to fans that a prescreening of the film "Precious," due out later this year, dislodged "some raw emotions and brought me to some things and places in my life that I needed to deal with but had long forgotten. It brought back memories so strong that I can smell and taste them." 

Perry is an executive producer of the movie, which tells the tale of Claireece "Precious" Jones, an illiterate, obese 16-year-old girl from Harlem who is emotionally and physically abused. 

The 40-year-old producer says he can identify with the character, and he recalls a number of incidents from his childhood. 

Emmitt Perry Sr., a construction worker, uttered profane insults at him and relentlessly beat and belittled him, Perry says. The random, violent beatings were commonplace until Perry was 19, he said. 

"You ... jackass! You got book sense but you ain't got no ... common sense," he quotes his father as saying. 

"I heard this every day of my childhood," says Perry. 

Attempts to reach Emmitt Perry Sr. for comment were unsuccessful. 

Tyler Perry was born Emmitt Perry Jr. but changed his name to distance himself from his father.
