My boss was sitting at his desk and called me over...
He was sitting there in a pair of what he called prototype mens tights, they had been designed to allow the penis freedom with it's own nylon sheath and his balls in a separate sac.
To be honest although he looked silly, I could see men buying these
He showed me how even having an erection could be accommodated as he wanked himself to stiffness.
He even explained how a little design adaptation at the tip of the sheath would allow men to piss without taking the tights off
