Thank you all for sharing, I appreciate it very much, you have been wonderful and I've enjoyed every single respond.

I realize that I have much to learn about my fiance's needs and desires with CDing.

I agree Mrs. docrobbysherry, he has told me that he has been alone for months in a row and the "urge" its not there, just as you say, but as soon as he can't do it for whatever the reason, that triggers the "urge" back.
