Here's some 90's nostalgia we can all get behind: back in those halcyon days, the condom use of youths was on the rise. A decade ago, condom use amongst 15-19 year-olds reached its peak at around sixty percent. Since then, the rate has stalled; alarmingly, its even declined in certain demographics. Although a study from 2011 shows that the percentage of teens using condoms during their first sexual encounter with a person has risen all the way to 80 percent, it also finds that that number quickly drops in subsequent sexual encounters.
The good news: this information, coupled with the recent data from the CDC that show teens are having fewer babies than ever, indicates that teen girls are using birth control effectively. The bad news: obviously, birth control does not prevent you from contracting STIs. If you take a condom precaution once with a person, that doesn't magically exempt you from contracting the clap from your following sexual encounters with that same person. So — youths (and everyone): if you or your partner has not been tested, put on a damn condom. The end.
