I was in my early 20s, stationed at one of our Air Force bases in Europe. This was back in the 80s, where the dorm rooms at TJ had 2 beds and shared a bath with another room, called a 2+2. I shared a room with another airman. We had stacked our beds into bunk beds to give us more floor space, and I had the top bunk. I got along with my roommate pretty well; we occasionally partied together, but not too often. We were in different units and everyone tended to hang with the guys in our own units.
Pretty much everyone went out and got a good buzz going every night. I know I would sometimes drink until I stumbled back to our room and passed out. I was always horny and was having a hard time getting laid. I beat off pretty much anytime I had the room to myself, and even remember trying to see if I was flexible enough to suck my own cock a few times. (I could just barely lick the tip - not very satisfying). I had no conscious thoughts of bi or gay sex, but I do remember catching glimpses of my room mates cock... now I wonder if those were deliberate.
