Intestine Stagnation?

1. he does not have a problem. his situation is just helthy and lifeprotecting reaction to forcing. why should his intestines heal just to endure such … again.

2. spraying thich water on intestinal fire… it is only natural that the fire might get hurt. The dilemma between consequences of blowing the load and killing the fire of gut. Is the result of lust. strong creature.

The pattern.
