Using a condom during sex seems pretty simple, right? You open the package, put it on, and toss it in the garbage when you're done.
The answer is not up for debate: It's one time only. And while it may seem obvious, there apparently are enough people reusing condoms that the Centers for Disease Control and Prevention had to tweet a sex-ed lesson.
"We say it because people do it: Don't wash or reuse #condoms! Use a fresh one for each #sex act," the CDC STD account wrote in a July 23 tweet.
The tweet elicited a host of reactions, ranging from shock to horror.
