Boitumelo “Boity” Thulo's mother Modiehi Thulo set Twitter tongues wagging when she commented on anal sex.
Tweeting to her more than 48 000 Twitter followers Modeil said: “I’ve seen many, many people dying from constant anal sex.
The muscles on the anus don’t contract back after sex, once the sphincter muscle laxity is reached, nothing can be retained. Hence people start wearing adult napkins.”
Modiel sparked a huge debate about the health risks of anal sex.
In response Joburg-based family doctor Lerato Masemola shared her insights on this subject during a lengthy Twitter thread.
