Squash blossems

Squash blossems

I have had more blossoms on my summer squash plant than I can count, but no fruit. I got a book yesterday that describes how to pollinate the blossoms yourself, showing the differences between the male and female plants. It says the females have a swelling behind the flower. Well, I don't see any swelling on any of the flowers. Is there such a thing as an all male plant? What's the deal here?
