Actor Will Smith described having “rampant sexual intercourse” in his new memoir, “Will” and said that he had so much sex, he would become physically ill while having an orgasm.

Smith wrote in the autobiography the feeling of being so disgusted with himself that he would gag and sometimes vomit while having sexual intercourse after a teenage breakup.

The actor said he was heartbroken over the breakup, especially since his girlfriend cheated on him. To get over the relationship, the 16-year-old Smith became promiscuous and said he had “rampant sexual intercourse” with many women.

“I desperately need relief but as there is no pill for heartbreak, I resorted to the homeopathic remedies of shopping and rampant sexual intercourse. Over the next few months, I went full ghetto hyena,” Smith wrote. “I had sex with so many women, and it was so constitutionally disagreeable to the core of my being, that I developed a psychosomatic reaction to having an orgasm.”

He added that intercourse would make him physically ill and sometimes vomit.

“Literally make me gag and sometimes even vomit,” he added. “In every case, though, I hoped to God this beautiful stranger would be ‘the one’ who would love me, who would make this pain go away.”

Smith also described being mortified when his mother caught him and his high school girlfriend having sex on the kitchen floor.

The two teenagers were “doggy-style” on the floor when Smith’s mom came into the kitchen to make coffee and turned on the light.

“Mom flipped the light switch as she had done tens of thousands of times before. But this time, her eyes landed upon her eldest son and his girlfriend deep in throes of reckless lovemaking.”

“As a teenager, outside of physical injury, you cannot feel worse than having your mother catch you and your girlfriend doggy-style on her kitchen floor. I’m still not exactly sure why I did what I did that night,” he wrote. “To this day, I have no idea what I was thinking. Of all the experiences I am sharing in this book, this is the individual moment of personal behavior that makes the least sense to me.”

Smith’s girlfriend, Melanie Parker, had been staying with the Smith family temporarily after her mother went to prison for killing her father. His parents had allowed Parker to stay with the family as long as they respected the household rules. Smith said the couple lasted three months before breaking the rules and having sex.

Smith’s wife, Jada Pickett Smith, congratulated her hubby on Twitter after his memoir became the New York Times #1 Best Seller.

Smith’s memoir “Will” was published on Nov. 9.
