Though a gender stereotype, the old adage is true. For men, physical intimacy is the bridge to emotional intimacy. For women, emotional intimacy is the bridge to physical intimacy. Sex is a powerful motivator--one that is wired into the deepest recesses of our brains. In other words, God wired us that way.
Rob wants to feel close again to Celia. And, he wants sex to be that bridge. We have yet to see Celia's response. But, I give credit to Rob for the efforts he has made to re-connect after the conflict over Celia's needy mother. Celia, like many wives, will have to decide if she is willing to share her body with her husband to foster a reconnection beyond just the sexual act itself.
We all have to be thoughtful about how we use our sexual power with our spouse. Irreparably harm can ensure when approached cavalierly. On the other hand, the strongest bonds can be forged when approached in a spirit of authentic sharing.
