In college, I masturbated in the restrooms, in the library, in a couple of empty classrooms, in the computer lab, a stairwell and a parking garage. At work, I frequently masturbate in the men's room.
School bathrooms. I've also sneaked into the girl's bathrooms to masturbate a few times when I was in high school, if I were to confess honestly. xDD And then once or twice in bathroom at a local public library as well. Masturbating at work is easy for me, so I do that if/when I need to.
yes to both. In the boys bathroom many times but always secretly in a stall. At work either in the bathroom or in a pota potty
Yes, if I get hard, there is no other way to get it back down. I go to the restroom if there is no other private spot.
Never jerking off isn't something I do much of. It would take like six months of no sex before I would jerk off. but if there is a female that ask me to an wants to watch them I will jerk off just for her. But never got so turned on I had to spank it.
School, work, whenever I felt the urgency and had some privacy. I’ve done it in stop and go traffic a few times. It helped pass the road rage! And in my youth on long interstate drives.
