i'm bored with him - but probably not how you might think

my husband and i have always had an amazing sex life. he has always been a very giving partner and has been good about paying attention to my needs. however, it seems as though he has fallen into some sort of "ritual" or "routine," for lack of a better word. the same moves, over and over. i can pretty much expect what he's going to do, and in what order. i really hate to say it, but i'm getting bored, and it's turning me off.
please don't tell me to try porn or toys or role playing, because we've already incorporated all those kinds of things, and they don't help anymore. bringing other people into the bedroom is completely out of the question as i have seen what that has done to other people's marriages.
the problem is that i have no idea how to tell him.
my husband is extremely sensitive to criticism. i know "that's his problem" as i'm sure at least one person is going to say, but you have no idea how complicated it is to point out to him when he is "doing something wrong."
i guess i'm just trying to put my feelers out there to see if anyone else has encountered a similar situation with their spouse and could share with me what they said or how they handled it. like i said, i don't really need to be told to put on some sexy lingerie when he comes home from work or try some new ----- moves on him. i can write a book on ----- s.
i need advice on how to approach him about his sexual behavior in a way that won't threaten him or make him feel like crap. i guess that's the best way to sum up my problem.
i'm sorry if i'm rambling. i'm so tired it's unbelieveable. :) thanks for reading, grrls.
