The other day, I tried to sit with a wide enough "stance" to reach into the (vacant) neighboring stall. No dice - my trousers and underwear made it quite impossible. I had to move my whole body over to get underneath the stall divider.

You might marvel at this, since you know that I am not stranger to toilet room sex. Out gay guys don't have to do the 'code'. I just stand at a urinal jacking off in front of my prospective partner. Very direct, works great.
