Just imagine the headlines
The number of studies on the effect of depriving human infants and juveniles of sexual rehearsal play is exactly and precisely zero. Moreover, anyone who tried to conduct such a study would risk imprisonment for contributing to the delinquency of minors or for being obscene. Just imagine the headlines and the fate of a research grant application requesting funds to watch children playing fucking games! Imagine, by contrast, headlines accusing parents, priests, and teachers of criminal neglect and abuse of children by depriving them of sexual rehearsal play or punishing them for it.
