There is an apparent belief among conservative men that female birth control (ie the pill) works the same way as a condom. (See here and here.)  Guys, I know you want your wives to be virgins, but I’m also pretty certain you want the women you sleep with before/outside of marriage to not get pregnant. So, let me explain how the pill works, in language you can understand- it’s like Cialis for daily use.

One pill, every day. Cost and quantity do not scale with sexual activity. Taking the pill does not make a woman a slut or a prostitute.
