I am not a fan of the courtesy flush, except in dire poo circumstances. I find that the risk of murky ass-splash is too high, especially in those high-volume scenarios. (To be fair and balanced, the air vortexes created by the flush can have a pleasing wafting / cooling effect on the sack, but Gold Bond also provides this.)
The aroma is an unfortunate side-effect, especially after an extended session, which has occasionally caused nasal discomfort to my sweet girlfriend after my famous Saturday Afternoon Specials(tm). Despite my misgivings, it would behoove me to find a way to incorporate this technique into my approach to Runway #2 at home, but otherwise I will forego its application. I will report on my findings and hope to learn to love the courtesy flush in the process.
