What Is The Best Medicine For Birth Control?

What forms of birth control are available for me and my partner? We are both disease free and are not comcerned about sexually transmitted diseases. We are only worried about unwanted pregnancy. We do not want to have a child in the forseeable future as she has 3 and I have 1. We do not like the feel of condoms and do not want to worry about protection on a daily basis as with the pill.
