Don't start unzipping until you're protected by the privacy of the urinal. Don't step back until you've thoroughly shaken off and closed your pants again. Reduce noise at all costs. Grunting is not acceptable. When you find an unflushed toilet, leave it alone and use another.
New rules apply for dealing with the females.
Never, ever, comment on how they look in the morning. Don't ask what the little wastebasket is for. If urinals are present, only use them when absolutely no females are around. If you are noticed by a female, try your best to ignore her presence until you're dressed again. Use them only if absolutely no other option is available.
