I went through that for years with my ex-wife though I would stop short of begging.
She was cold when it came to the physical part of our relationship and just as cold
emotionally. The only time in our marriage that she ever initiated physical contact
was when she wanted children. Other than that she was pretty icy.
It was a long lonely road being married to her and after growing up with a mother
that was emotionally unconnected my ex truly was a very bad choice for my MI.
