When I am sleep depraved, because of certain shifts, like today at work, I sometimes get spontaneous wood, even though I'm not thinking anything dirty and it does NOT go away.
So when I really want it to go away, and want to stop falling asleep, the bathrooms are extremely private. Big wood doors almost from roof to celing. Drywall walls on either side of you. Heavy duty door handles. did it once and woke right the hell up afterwards. Never caught.
i always masterbate at work.....i work nights,so on my hour break i lock myself in the staff room and its all good....helps the night go,something to look forward to...xxx
