Since I don't ride as much in the winter I gain quite a bit of belly fat that makes being in the drops uncomfortable and "ball crushing" but as the gut goes away I can stay in the drops longer and well before winter comes it's not an issue.
Then winter comes and the process starts over.
saddle height relative to bars, tilt, fore/aft; How I hang my junk in my cycling shorts and other suggested things helped me to various extents too. And though you like that particular brand of shorts, they might not be giving you what you need when in the drops.
