Chastity and orgasm denial discussion

Alright here I go with what might seem like an odd question to some, but it’s directed at men who are in chastity—purely chastity, not sissification or its accompanying traits—and just the core experience. How do you feel sitting down when you need to urinate? I’m also keen on hearing from Keyholders if any of you have one. Thanks in advance for all your comments.
