I know the smell you're talking about but I wouldn't say unwashed coochie, more like sweaty feet. I'm sure there's some nutritionist or chemist out there who could explain what chemicals go into creating that odor.
The short answer, there's nothing wrong with your chicken (rotten is rotten, you'd know if it was spoiled) just wrap the individual pieces in plastic wrap after cooking THEN put them in the tupperware or freeze them. Reheat them in the plastic wrap. Stink thwarted. It smells fine once it's reheated.
