I just masturbated in the bathroom at work
Did you find it  arousing to masturbate in the bathroom at work?
Yes, I felt a unique sense of ecstasy after I ejaculated in the urinal
You should probably wait until you get home to take care of such private matters. Restrooms at work are public, and you should not be masturbating in public. You'd be embarrassed if one of your coworkers came in and saw you.
I can't get it up at home. I miss the danger of maybe getting caught.
Wanting to get caught masterbating in public is no excuse for doing this in the bathroom at the office, because it is still inconsiderate towards others. Find another way to stimulate yourself that isn't in front of others.
