“Training by engaging in sexual intercourse”, Tyson reveals his fun and first defeat in boxing

A little over 21 years ago, on February 11, 1990, Mike Tyson suffered the first loss of his career in Japan against American James Douglas after 37 victories.

Tyson discovered in his autobiography what caused the loss. I didn't want to fight. All I cared about was hosting parties and having sex.

During those days, in Japan, I had sex with waitresses. I also met a young Japanese girl with whom I had relations before.

When my wife went shopping, I went to this girl's room. This was my fight training. One day before I was in the ring, I stayed with two waitresses at the same time. Then, with two other girls.” He said Tyson.
