I agree with all the above, and can vividly recall an incident that almost ended in disaster. My partner and I had spent an idyllic afternoon engaged in naughtiness and afterwards, we decided to go out and get something to eat. While we were at the restaurant, I had a sudden wave of peristaltic action, no doubt brought on by the earlier anal minstrations. I excused myself from the table and made my way to the ladies'. Sure enough, I did need to evacuate. Problem solved, I thought, and went back to the table. Five minutes later, I was struck by the "blugh" feeling you so eloquently describe, GG. I knew if I even looked at food, never mind ate it, it would be the end of me. We hadn't ordered yet, so when he asked what I wanted, I just said a diet soda would suit me fine.
My biggest problem is that due to neuropathy, my body lies to me. You know that old saying, "never trust a fart"? Well that fits me to a T. Sometimes, when I think I can wait, I really can't. On this particular occasion, when the peristalsis kicked in again, I decided to ride it out. It was almost a huge mistake, and when I finally got the message and left the table, I almost didn't make it to the loo. Now I know, enema before, immodium before, and very little to eat until a few hours after.
That's my story, and I'm stickin' to it.
