There is more to marriage than non-existent orgasms. (Isn't that why God created fingers, vibrators, and hand-held showerheads?)
I feel guilty because he is my friend and I have been with him for half of my life. He is a good guy, just not good for me.
He is not manipulative, just very dependent on me for his stability and happiness. (No one can make you happy but yourself. I know this, he doesn't.) I have never been a worrier. I am laid back, loyal, outgoing, determined, and nuturing. I always take care of everyone around me. I guess that is another reason for the guilt. I don't want to take care of him anymore.
