Why do they call sex "the birds and the bees"?

Because birds and bees both fertilize flowers, they stick themselves or their beaks in the flowers in order to fertilize it….sticking stuff in somewhere kinda mimics sex in a way I suppose….

The birds and the bees is an english language idiomatic expression that refers to courtship and sěxual intercourse and is used as a teching device to talk about sèx and pregnancy. The bee carries and deposits pollen into flowers this makes for and easy visual and explanation on the whole idea of male fertilisation. And the bird laying eggs is a visual on the female ovulation.

because when you have sex you does feel like you flying high like birds and bees lol thats what i learn

They are both cross-pllinators. Both animals get pollen (sperm) on their bodies when gathering nectar. After traveling to a different plant, the pollen rubs or falls off of their bodies into the stigma (v@gina). It travels down the long tube of the pistil which I guess would be the equivalent of our internal os….Then it reaches the ovule containing the egg so to speak. Sexual reproduction in plants is facilitated by bees, birds, and other pollinators. “The birds and the bees” is just a cute little euphemism of sex!

You know something? I always wondered that.
