Like so many children, by age suzie understands that genital self-stimulation is pleasurable and by this age she is capable of experiencing orgasm through masturbation.

This happens by age three to four. Children develop sexual behavior often much earlier that conventional thinking indicates. It is up to the parents to teach Suzie when it is appropriate to engage in such behavior. In the past, children were taught that masturbation was wrong, but this may vary today.
