There are several times in the Bible where God commands that the wife submit herself to her husband. Being the "Miss Independent" that I am, I'm not too fond of this part, but I try, I really try to submit myself lovingly to my husband.
Part of this submission also includes the marital bed. In 1 Corinthians, it clearly states that once we are married, we are no longer in complete control of our bodies.
The reason I am even addressing this is because I believe that as a society, it has become the norm for women to withhold sex as a form of punishment when their husband makes them mad or doesn't live up to some expectation. I also believe that men see sex as a joke, something they are "entitled" to from any woman that they meet.
THIS NEEDS TO STOP!
Women, your husbands do not have to jump through hoops in order to receive physical pleasure! Men, your women (wives - preferably!) do not "owe" you anything!
God gave us sex as a way for husbands & wives to connect to one another in a way that not just anyone can.
