i never go in my own room.
My ex who introduced me to naughty peeing would take me to a hotel for a week but the deal was if i needed to go to the toilet i had to find somewhere apart from the bathroom or room to go. I would go in the hallway on the carpet, in the elevator, in a washing machine sometimes with someones clothes in it, on a car in the parking garage, down the stairs, in the spa or sauna or gym.
As for guilt it doesnt cause permanant damage and the hotel already pays cleaners so who cares.
