Man, cukes are crazy. I say pluck the fruit and eat it, and plant those puppies. Just my 2 cents. As far as male and female, cucumbers are monoecious, meaning "one house." This means both male and female parts are housed in every flower, like most plants. There are dioecious plants, the most notrious of which is Cannibis, in which there are male plants and female plants.
I think the big issue with cucumbers and pollinating is that plants must be visited by several pollinators in order to assure nice straight fruit. If they don't get all their carpels fertilized, fruits develop in a curly or bent form.
Long story short, your flowers have boy parts and girl parts, and thus can pollinate themselves if you give them help, eg. gently run a Q-tip inside the flowers and visit several with the same pollen covered q-tip.
Once they're outside, they'll do their thing. Bees, wasps, and other pollinating insects will likely give you more Cukes than you'll know what to do with. If not, use the above Q-tip trick, and you'll have so many cukes, you'll have to learn to make pickles to use them all!
Enjoy!
