Birth control!?

I suggest trying a diaphragm, that way you aren't putting medication into your body and as long as you make sure to use it every time you make love it is 99% effective. I am not sure what the rest of your question is about but a really great website for answers about is Sue Johansen's site called "Talk With Sue". It is based on her TV talk show of the same name. I've listed the address for the site below.
