If you do not see flowers of

If you do not see flowers of different sizes (small and large), then they are likely all male flowers (the small types). The larger female flowers should start to appear soon. If pollinated, the female flowers will form the fruit.

 

If you do have both male and female flowers, it could be that you do not have enough pollinators. In this case, you might want to try hand pollination. To do this, in the morning (best time), take some of the smaller male flowers and rub some of their pollen (on the anther) onto the top of the tall structure in the center of the larger female flower (top part is called the stigma).
