What is it that you think about just before you get a condom? Sex!

The line is structured like a call-and-response joke: it poses a rhetorical question and immediately supplies the blunt answer. Its point is to puncture embarrassment or euphemism around contraception by stating the obvious—condoms are obtained in anticipation of sex. Read as a piece of sex-positive humor, it normalizes planning and safer-sex behavior while also highlighting how social discomfort can make purchasing condoms feel fraught or awkward. The punchline’s directness functions as a corrective to coyness: if the goal is responsible sexual health, then acknowledging sexual intent plainly is part of that responsibility.
