Please choose the correct ending to complete the given sentence: Health: [header] How to hold in pee when you can't use the bathroom [title] Visualize closing your urethra. [step] Your urethra is the opening to the outside through which urine exits your body. Imagine squeezing muscles surrounding the urethra while allowing your other muscles to relax.

Ending1: These are the same muscle you would squeeze if you were trying to stop a stream of urine. Relax the pelvis and abdomen to avoid placing additional pressure on the bladder. Ending2: The urethra is also where urine evaporates (probably for a long time) when you urinate. [substeps] If you don't draw much urine from your urethra, you probably don't need to use it quite as often. Ending3: [substeps] If you think you should close it, then don't! You may accidentally add a wall to your urethra. Then, imagine a pin cushion going behind it. Ending4: Picture a flexible adhesive seal flexing over your urethra. [substeps] Concentrate on visualizing the air coming through into the out of the urethra.
