The 53-year-old actor admitted he was desperately trying to find love with the sexual encounters.
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. But invariably, there I was, retching and wretched. And the look in the eyes of the women even further deepened my agony.”
Elsewhere in the book, the Aladdin star recalled how he thought he would “die trying” to satisfy Pinkett Smith in the early stages of their relationship.
He wrote: “We drank every day, and had sex multiple times every day, for four straight months.
“I started to wonder if this was a competition. Either way, as far as I was concerned, there were only two possibilities: (1) I was going to satisfy this woman sexually, or (2) I was going to die trying.”
