Looking for punishment

My master and I have agreed that he has control of when I’m allowed to use the bathroom. It’s a long distance relationship which makes punishment hard. I have to ask him permission before peeing. We’re trying to come up with a punishment for when I go without permission. (If he’s asleep when I have to pee, there’s a time difference as he is in Germany and I am in the US, I have to let him know I peed but I don’t have to get permission.) Anyway we’re looking for a punishment that I won’t want to do if I don’t have to. However I am very masochistic so it’s hard to find something that works. We’re thinking that since my urethra is what misbehaves maybe that’s what should be punished. However it’s kind of hard to sound yourself when you’ve got a cunt (I’m a trans man.) we also thought of putting toothpaste on my clit (which I like at first but would eventually have me begging him to let me wash it off.) any way just brainstorming here and was wondering if you guys had any ideas.

I understand the excitement of being controlled as i am submissive. and control of bodily functions is very sexy. but with the time differences its difficult. remember its not good to hold your urine too long. can cause uti or back up into your kidneys causing major problems. you might discuss this with your master

OP, you're urethra is not "misbehaving". It is doing what it's supposed to do. As @toshe63 said, it's dangerous to hold your urine for too long.

Thank you for your concern but while we play this way we have the express agreement that I will not hurt myself and that first I would disobey him. I like being punished. If I didn’t he wouldn’t punish me for regular bodily functions. He’s always checking in and reminding me to be safe. Yes we want a punishment that isn’t accidentally a reward but I won’t agree to it if it’s something I would actually want to avoid so badly i’d rather hurt myself by holding too long.
