My wife suffers from lazy bowel syndrome. It means she doesn’t go regularly to the toilet, sometimes it takes 3 or 4 days until she poops. For these emergencies, she has a drawer full of rectal laxatives such as Minilax, Microlax, Dulcolax, whose content should be inserted directly into the rectum. These are better than oral solutions for her, because the effect are almost instantaneous.
And then we discover that my cum in her colon has the same effect! 
And it’s natural, highly available, fun and for free.
Now I need to return to that thread How does your partner let you know they want to fuck? and add one more sentence: “Honey, I need you to do the cocklax on me today”.
