My Wife Said I Was Unable To Satisfy Her In Bed - Malcolm X

Slain civil rights icon Malcolm X acknowledged that his marriage was failing because he was unable to satisfy his wife in bed, it was learned on Sunday.

The stunning revelation was made in a 1959 typed letter written by Malcom X to his mentor, Nation of Islam leader Elijah Muhammad, according to the New York Post.

In the letter, X says that his wife, Betty Shabazz, complained that her husband had 'never given her any real satisfaction' and 'said to me that if I didn't watch out she was going to embarrass me and herself (which under questioning she later said she was going to seek satisfaction elsewhere).'

The letter reads: 'The main source of our troubles was based upon SEX.

'She placed a great deal more stress upon it than I was physically capable of doing.
