Hello and welcome to e health forum.
The description of the history is inadequate to make a proper diagnosis.
Lacerated colon, usually occurs only with penetrative injuries, like road traffic accidents or knife stab injuries. Other conditions include use of penetrating sex toys.
The main issues in such conditions would be internal bleeding which may result in hypotension, loss of consciousness, severe crampy abdominal pain or tenderness, fever, nausea, vomiting, abdominal distension, bleeding from the rectum, etc.
Such conditions are a medical emergency and people lose lot of blood and many times it can be very fatal.
Hence in case, your husband, has been involved in such activities, and is in severe pain, you should not wait to make a diagnosis of the condition yourself. You should take him to the nearest emergency room, so that timely help and treatment can be initiated. This will prevent any form of complications that can occur due to delay in treatment.
The last thing, you should worry is about saving a life and not embarrassment of answering questions.
I hope this helps.
