Husband and wife enjoy exactly the same rights under God. Actually, Paul does not speak in terms of rights, but responsibilities. It's not a matter of stirring women or men into standing up and demanding their rights. On the contrary, by each voluntarily giving up their own rights, they ensure the rights of the other, by fulfilling their responsibilities to them. The way to ensure rights is to give them up, in God's topsy turvy guidelines for successful marriage.
Sex is an area of great potential for hurt, emotional blackmail, and conflict.
That is, don't go for too long without meeting each others' sexual needs, and only by mutual consent, lest one of you be tempted to have them met by someone else. Verse 5 means that Christian men are responsible to do all they can to meet the sexual needs of their wives. It's not a one way street. Then think again. God thought of that idea long before Germaine Greer or Naomi Wolf.
