Cucumber flowers and the sexes

In this new hobby, I've taken on some reading. They don't call these years the information age for nothing. There's a ton of information out there. I was reading about cucumbers. I have 3 vines and one is doing super well.
The interesting cucumber fact is the first flowers are the male flowers. Following a bit later are the female flowers. Pollen has to make it from one to the other and if all goes well, just below the female flower the baby cucumber will begin to form.
The male flowers are slightly larger and all of mine have been really good-looking hearty flowers. The female flowers may be slightly smaller and sometimes more hidden under the broad leaves of the vine, but they are the creative and productive members of this little family. Amazing.
