While there is a huge amount of variability in the size of different people's anatomy, as a general rule of thumb, the anus is about an inch and a half to two inches in "depth" and the rectum is about six to eight inches long. That means between 7 and 10 inches of "straight-away" before you hit a sharp turn at the colo-rectal junction, where the large intestine feeds into the rectum.
While you can find video's of people snaking 30 inch long jelly dildo's up their rear ends, the fact is, these are very soft, flexible and simply follow the curves of the natural anatomy. Some people can do that, others cannot, as the curves inside may be too abrupt (and the nausea that comes from banging on the inside of the intestinal walls may be too intense) for others.
This question, however, concerns just going STRAIGHT IN with a rigid (plastic, metal, or glass) toy. What is the MAXIMUM length....be it a narrow or thick toy (doesn't matter), but what is the MAXIMUM LENGTH toy you will or have accommodated anally?
