Abstinence works however at 100% effectiveness (for both prevention of conception and prevention of spreading disease) whilst condoms work at, what is it, about 97% prevention of pregnancy for experienced users and much lower for inexperienced users. I don't know the figures for disease spread but presumably things like genital warts and pubic lice aren't hindered much by condom use.
I don't think this is really the place for this discussion/ your snide remarks.
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"
