If we assume that you're otherwise young & healthy, it's likely this is more a psychological issue than a medical one. Of course, if you have any concerns, you should get evaluated by your family physician for an enlarged prostate
, decrease bladder contractility, or spinal cord injury
In fact, it's best to avoid such (over-the-counter) medicines, such as those for colds & allergies
, eg phenylephrine
, phenylpropanolamine, and diphenhydramine
, etc, which cause prostate capsule contraction
& decrease bladder strength.
My suggestion is to be straightforward w/your potential employer and tell him/her of your medical situation (paruresis) so that they can give you more time/room to produce a urine
With that in mind, ask if you can use a private, executive, one-stall facility where you can be frisked before going in (to demonstrate that you don't have a spare urine bag on your person) yet be allowed to urinate in private. You might see if drinking lots of fluids (caffeine
, perhaps?) can help you over come this - in an attempt to overwhelm your inhibitions. Another solution that's been around for some time is to listen to running
water, eg turn on the faucet (not popular w/environmentalists). Either that, or go see a behavioral therapist
, as i'm not aware of any medications to make you urinate upon command.
