Binge and purge, I went through that a few times when I lived at home, (though at the time I only had some diapers and no clothing as this was before internet days and thought I was the only one (HA). Now the funny thing, I've long moved out, have my own house...yet I STILL hide my diapers and ab stuff. (Well ok for good reason, I don't want my cleaner coming across them).
I potential thought, I like the idea of locking up your stuff as I did the same...but I sorta threw in a decoy. I covered the top with a bunch of mags/comics (I think they were Heavy Metal) and left it open in plain sight for all to see while I was in the room so at a glance it was a trunk full of books nothing else...Curiosity quelled.
