If you're fortunate enough to have never been similarly outfitted -- which is usually done during hospitalization, surgery, or for people otherwise physically/medically unable to get to a bathroom or even use a bedpan -- it involves passing a flexible tube (about the same circumference as a pencil) all the way up through your urethra into your bladder. The tube has a little balloon on the tip, which can be inflated once it's in place to keep it from sliding back out. Once the catheter tip is inside your bladder, urine flows freely, no longer within your control, directly from your bladder into a bag that can be attached to your leg.

Davis is not at all the first politician to have used a catheter, though the practice is not widely discussed. Senator Rand Paul, a doctor by training, captured the general sentiment nicely this past March when he explained, after a lengthy filibuster: "I've put them in [for patients] before, and I really decided against it."

Strom Thurmond famously opted to keep a bucket in an adjacent cloakroom, where he could relieve himself while still keeping a foot on the Senate floor. During a 2001 filibuster, St. Louis Alderwoman Irene Smith had aides surround her with tablecloths while she relieved herself in a trash can in the middle of City Hall. O beautiful for spacious skies.

Urinary catheterization is a very common and generally safe procedure, though. Of course nothing is 100 percent: It increases your risk for UTIs, and very rarely, something inside of you gets punctured or ruptures.

Most people rate the experience somewhere between unpleasant and quite unpleasant. Though less common superlative accounts do exist, like that of karmic alignment for misogynist-of-note Tucker Max: "The act of inserting that fire hose into my penis was so horribly painful it made me forget what was, to that point, the worst pain of my life."

The discomfort and potential complications of a urinary catheter may seem a small price to pay to influence major legislation, though. The last time a Texas session got going in the abortion arena, they ended up requiring women seeking abortion to undergo a vaginal ultrasound and "hear a description of the fetus" at least 24 hours ahead of the procedure, in addition to cutting the state's family planning budget by two-thirds. Researchers at the University of Texas at Austin now say that as a direct result of that cut, 117 Texas family planning clinics stopped receiving state financing and 56 closed. 144,000 fewer women received health services, and 30,000 fewer unintended pregnancies were averted in 2012 compared to 2010.

If you do feel called to catheterize yourself for the greater good (or for evil, depending on your perspective), the National Institutes of Health offers important guidelines: " ... Use firm, gentle pressure. Do not force it. Start over if it is not going in well. Try to relax and breathe deeply."

That's actually good advice for anything.
