guilty! i manage a construction business (the office work, not the site work) and all of my people working in my dept are men (25ish to 40). while masturbation isnt part of our official office policy, i think there is a mutual understanding that guys have needs and that its okay if someone wants to spend their lunch break jacking off in the bathroom.
we all know how uncomfortable it can be when you want to stick you hand down your pants but you cant cause youre at work. i honestly think that my guys are more productive if they get the chance to relive themselves.
i know i have had to walk around the office trying to conceal a massive erection. i know how good it feels to be able to lock the office door, unzip, pull your meat out and masturbate till you cum.
i also think the guys i work with respect each other enough not to make a big deal out of it or do anything that would make the other guys uncomfortable. office j/os are a single man operation, and i think my employees are happy with the current system.
