I can relate to this...
I had 2 mortifying incidences this summer. For those of you who don't know, I deal with urinary issues daily, so im pretty much used to dealing with that. But, once in a great while, and I'm not 100% clear on the cause of this, but if i had to guess its overflow from constipation, my bowels misbehave leaving me with a mess down there. That happened to me on the night of closing banquet 2 hours before i was suppsed to get dressed adn ready. I was too mortifed to move for several minutes. I'm like, oh crap (yes, i know..but pun not intended) what do I do? But I got through it.. I ended up throwing away a washable underpad which got soiled after cleanup. I did'nt have ready access to a private shower..or wipes at the time, so i had to use toilet paper.. and that aggravated some hemmroids i had.. ouch!
The second time, I overestimated how long i could wear a confidry and noticed a wet spot on the back of my jeans. Thankfully, no one said anyhting to me. Also, once i walked out of my cabin without snapping my onesie.. and it was showing in the back.. a couple of teens saw it... and giggled..but nothing was said to me directy.. not much I can do about htat except just make sure im snapped before i leave from now on

. I am open to considering alternate management strategies as well as possibly doing some biofeedback in a LIMITED fashion to reduce these instances..
Peace out!
