Yes. Received my first blowjob in the back office of the wine shop where I worked in college.
Yes several times, usually in the guy's office after normal work hours on the carpeted floor or on his desk, & a few times in a supply closet during the workday. Those latter ones were quickies standing up, or with me bent over a pile of boxes, or me simply kneeling & doing him orally,
Nope. I've masturbated at work during business hours but never had a sexual encounter (I have a list of possible coworkers that I would not say 'no' to but those remain fantasies, as they should).
Learning to draw the human body becomes a lesson of another kind.
The woman by the pool shared her art ... and so much more.
