Holding your pee for a little too long ONCE in a while is not harmful. People do it at their jobs or while running errands all the time, or before ultrasounds. For women, a full bladder can stimulate the g-spot and makes for a magnificent orgasm (or "peegasm" if you release your bladder at the same time). Highly recommended.
If you're grossed out by the idea just say so but don't perpetuate myths about it being dangerous. For any healthy person who drinks enough water on a daily basis, it's not. ๐
