I have not masturbated at work. I have, late at night, had a little, um, activity in my office, but not alone, so that's another matter.
I have masturbated while stuck in traffic, much to the amusement of some truck driver I didn't notice until too late. I have -- long, loooong ago -- had sex in an airplane bathroom, and given someone a blow job on a motorway. So it isn't the publicness that weirds me out. It would take time, as Sexydisaster said, and the toilets are uncomfortable and unappealing. And even when I was younger, I never couldn't wait for someplace more appealing.
