Walked in on mid masturbating in male cubicle

So I forgot to lock the door. I don’t usually do this but I was stressed out at university and it was an enclosed cubicle (not in America where you can see under etc). Guy opens the door on me with a bull boner mid stroke.

He was actually pretty cool about it and we laughed it off through cubicles. Tbh he kinda spoke to me for a bit too long after think he may have slightly enjoyed the view.

Anyway I’m obviously mortified. I know shit happens but still.

Ever happened to anyone? Would you be disgusted or laugh if you were him? I know there’s a divide but I’m convinced everyone has done it once in their lives 💀
