Usually, the small male flowers emerge a little before the large female flowers. Occasionally, the reverse happens. Are your male flowers not opened at all yet? If so, you might wait a week or so to see if they do mature enough to open; if there are very few, you might select one after it opens and use it to hand pollinate the female flowers, allowing the others to remain on the plant. If the male flowers don't open at all, you might check local garden nurseries that perhaps have a zucchini plant for sale that contains a mature male flower that you can use to hand pollinate. Good luck!
