The post and discussion about the CDC's rimming warning was interesting. As someone who loves eating ass but hates gastrointestinal problems, I thought I'd share a trick I picked up years ago from straight friends of mine who spent much of the 70s and 80s exploring primitive Third World backwaters. In all their travels neither ever developed traveler's diarrhea, a happy outcome they attributed to daily doses of Pepto-Bismol as a prophylaxis.
Since I adopted this as a pre-rimming practice back in the 80s, I've had zero intestinal issues. Turns out the bismuth in P-B is effective at preventing intestinal bugs. I usually also take a dose after any butt munching session.
