YUK!
A 64 year old woman with colon cancer kept returning to hospital with
an infection around her stoma (the hole where the tube from her
colostomy bag is inserted). There was also a mysterious whitish ooze
emanating from it. After eventually inquiring into her private life,
the doctors found out that she led an active sex life. "And," she told
them, "when we're feeling really energetic, my husband gets his kicks out of
removing the bag and using my stomah!"
