Google “natural birth control” and you will come up with a bunch of pages including information about The Withdrawal Method. Really. ‘The natural way to get pregnant,’ as one of my colleagues astutely put it. [By the way, this image is from the Chocolate Kama Sutra.]
There certainly are a host of natural ways to control birth (including taking your temperature, using fertility beads to track your cycle, etc.), that would make sense for monogamous hetero couples who choose to educate themselves on and commit to natural methods (and I wonder if the woman has to have regular periods?).
But what about everyone else? We all have to decide for ourselves what is best for our own mental and physical health in any given sexual encounter. Do the benefits of using only natural birth control outweigh the benefits of using a condom to prevent STDs? What will be more damaging to my mental and physical health: exposure to an unnatural birth control method or unwanted pregnancy/abortion?
The key is informed choice, in my opinion. Educate yourself and commit to your methods, and know the risks, BOTH the risks: for pregnancy and STDs and for exposing yourself to the hormones or chemicals involved in unnatural birth control methods.
According to the folks at Tree Hugger, latex condoms are where its at as far as pregnancy and STD prevention, and they provided this great article:
how to green your sex life, which has great info on how to take care of the environment in bed.
By the way, googling “green condoms” turned up this lovely item: Shamrock Condom LOLLIES. Happy belated St. Patty’s Day!
