I have a few sets of Tzitzit Undershirts, but not many. Not even enough to get through the week. But one certain days, when I'm feeling especially spiritual, I will wear them, either tucked in or out depending on my mood.
But the thing is, I have this... medical condition. Suffice to say, it involves the bowels. Sometimes I can't make it to the bathroom in time.

Thankfully, the days when I've decided to wear the tzitzit and the days where I've had an.. accident... have never coincided...
Yet.

Every day I wear them I'm worried-- what if things go south? I'd never get them off in time. And I'd hate to see them defiled.
Should I stop wearing them altogether?
