It's probably just as relevant to see the question from a the other side. Is it important for women to fear their man? I think it is to some degree, but that the level of fear needed varies depending on how damaged she is. But as a woman you know that y'all will test a man's limit to see what you can get away with. If he has no boundaries you will walk all over him. For some, usually emotionally damaged women that boundary is willingness to get physical if need be, for others it's enough that he stands up for himself. You will not be with a man you don't have deep respect for unless you've made a conscious decision that you need him because of the biological clock or something. Respect comes from admiration or fear. Thus some submissiveness might be needed, not because I want it, I really don't, but because women seem want it. Coli women are the exception of course.
