I was in the Army through the 80's and early 90's....in the US and Europe. Gloryholes everywhere...ranging from just for viewing pleasure to full-blown (pun intended) opening that could handle the biggest cocks. Given the military's view on gays, it was amazing the action that went on. Education Center, gym, library, remote latrines along running trails, PX....you could get action ranging from a handjob under the stall to a good ass pounding if the dude wanted to open his stall. You could also meet up later for some fun in the barracks or off-post. Disease risk was much less, as all the military were tested annually for AIDS...the bigger risk was the str8 dude who had "cocksucker's remorse" afterwards and tried to turn his fuck buddy into the MPs. You could also hook up for action later at an off-post adult video theatre in the German town...back rooms where lots of fun was to be had.
There was/is a whole gay underground in all the branches of service....I was a barracks sergeant in Germany and lost count of the gay and straight couples that would come out of barracks rooms together...it was actually easier for the gay couples as they could pass as "room mates"...and no one would know, except for the headboard banging on the wall...:biggrin1:
