Hey guys, you ever notice that when you're getting frequent, vigorous sex over an extended period of time (weeks, months, etc.), your limp penis tends to be larger than when you haven't been having regular sex for an extended period of time? Or is this just me? My theory is that the various orifices act as a sort of natural penis pump. Maybe I should purchase a penis pump and do a controlled experiment.
Excellent test. And to have a meaningful experiment, we will set up 2 groups. One group to work furiously on pumps, and One group to furiously work on various orifices. We can even setup double-blind experiments if some of the owners of orifices are particularly ugly.
