Hi,
I think that there is really no point in your question of asking why is sex really important. It is subjective. Some have it high, others low. In your case, you don't find it important, but your hubby does. The question I think u should be asking yourself is what u are willing to do to balance the 2 extremes. Likewise another question I would ask u is that since sex is unimportant to you, why not give him free rein to do what he wants sexually as long as he is being responsible doing it? Based on how you framed your question, your answer will no doubt be a resounding NO. You will think of many reason why it is so, then I'd ask you again... Is sex really important ?
