Well speaking as one still in the "whips and cattle prods" stage I am both jealous of the stage that you are in and sympathetic to your current plight.
Sometimes when I look at my H with sexual longing he will actually say, "What?" (as in what are you looking at?). If he EVER looks at me that way it is after things have gotten started. The clear exceptions to this are vacations - he is just a different man on vacation.
What will it take to go to next level with your H? As NOP says - practice but I also wonder - what are his fantasies and could playing one or two out actuallly bring on some of the "naked lust" you are looking for. I know you don't mean "agression" in an S&M way - I realize what you really mean is more akin to your H being sexually self-motivated. Would a few sexual memories geared just to him give him a reference point?
