So I think the fertility awareness method is great for trying to CONCIEVE, but I wouldn't bet on it for actual prevention of sex.
Also recommended on the natural living lj community is the withdrawl method. !!! Theorectically, FAM and withdrawl COULD work, but in practice people in general are not attentive enough, and even with attention, all it takes is one sperm and one egg to get together.
Ironically, this pissant bitch at natual living is calling me a "fucking idiot" because I say that the FAM method is just a modern version of the rythym method; when at the catholic highschool my bf went to, they taught about monitoring fertility signs as part of the rythym method. Of course the teacher who taught it and swore by it was ALWAYS pregnant and had at least 5 children at the time.... I think a better demonstration of birth control is having a few months at least of not being pregnant?
