I don't agree with jack99821. There are definitely "strings" in my marriage, very strong ones.
I agree with djpen as well, if all things were perfect, I would only be with my husband, his libido would be the same as mine, his equipment would work.
As for an open relationship not working, it works for us. We have always been open sexually, not hesitant to try new things. It is really sad the situation he is in right now and he feels enormous guilt that he cannot satisfy me. He feels better knowing I am being satisfied sexually.
It has not caused strain on our relationship. I appreciate everything he is. And he knows that, he knows I come home to him, and has no need to feel threatened.
