Am I the only person that discusses abortion and post-coitus matters before I sleep with someone?

What? Do you people (men and women) think that everyone views these matters the same way you do? It's crazy the amount of questions that pop in this section about people being surprised by their partners post-coitus reactions. Don't want your kid aborted then why sleep with a pro-choice person and vice versa? Don't want to pay child support then why sleep with a person that is pro-life? Don't want your kid fatherless then why sleep with a guy who doesn't want kids? Common sense much America?
