Corn on the cob TOO sweet!

Corn on the cob used to be a summer obsession and binge fodder for me. But now it's gotten too sweet, and I just don't enjoy it the way I used to. Anyone else feel this way? Anything I can do to help this problem? Maybe there's a particular type I should look for, or a particular vendor? I usually buy it at Whole Foods, sometimes Shaws.

I like it very plain: steamed with butter, salt, and pepper. I don't like to add other flavors, like chili or anything. But maybe I need to consider this option to ameliorate the sweetness? By the way, I don't own a grill, so that's not an option.
