What type of birth control do most responsible couples use…pill only or pill and condom???
That largely depends on your stance on abortion and your ability to raise a kid. If you don’t like abortion, and you can’t/don’t want to raise a kid, the more forms of birth control the better. If you don’t mind having an abortion, the pill alone is fine. The pill has a failure rate of about .5%, pill+condom brings that number to near zero.
