Jonathan:

For some HD's, it is possible to continue a marriage with little to no sex if your other needs are met. Unfortunately, for many HD's like myself, my spouse gets and "F" in sexual fulfillment and an "F" in affection. Lack of desire causes the LD spouse to often avoid sex AND affection. Now there are other things my wife does for my marriage, but they are all pretty much meaningless to me. Sexual fullfillment is about 40% of my marriage needs, affection is about 40% of my marriage needs, and the remainder is 20%, and that is not enough to even create a tolerable marriage. My marriage will be made or broken just on my first 2 needs!
