My Husband Does Not Satisfy Me In Bed

My husband is the best man I could ever think of getting married to.

He is very caring and loving. The only problem is that he is not sexually active. He never initiates any kind of sexual gestures and neither responds to any. I have tried seducing him but he avoids me in a very polite and funny manner so that I don't feel bad. It's been months that we have had any intimate moment and I'm getting worried.

What should I do?
