The 50/50 marriage is an arrangement of trade-offs and compromises, with spouses keeping score so one person never gets more or gives more than the other. Serving and submitting to one another are replaced by an emphasis on getting what is rightfully yours. Marriages only work when each spouse is giving 100 percent.
Sex is the ultimate knowing of one another, and the ultimate expression of intimacy. The more intimate you can be with each other, the more passionate and wonderful sex will be.
