Most women in this day and age cannot hack submission. That is because submission as a concept is not natural. It is taught to us and we are conditioned to train ourselves to be less than the man, and a lot of women who have gotten to the point of self-awareness, know they are as worthy as the man seated next to them.
From when you are a child, you are taught to be less assertive. You grow up watching your mother serving your father the way she was taught to, and she teaches you to do the same by the way she serves her husband.
