Hypothetically, you're taking a shower with your SO. It's sexy and naked and fun, when you realize you have to pee REALLY bad. What do you do?
Explain my situation, and climb out to use the toilet
Pardon myself and pee in the shower
Don't say anything and just pee in the shower and hope my SO doesn't notice
I complain of having a headache and end the shower, and then, when he/she exits the bathroom disappointedly, pee then
