Abstinence _education_ was the point of my comment. South Africa, the origin of this product, has been subjected to various abstinence-only education programs from outside sources and these are known to have negligible results[1]. Anything that instead acknowledges that people want to continue having sex and instead prepares them for the event - such as this product, and the accompanying video - is going to be far more useful in the long run.
"At present there does not exist any strong evidence that any abstinence program delays the initiation of sex, hastens the return to abstinence or reduces the number of sexual partners"
