Although the media loves to dramatize teen relationships, and even pregnancies, it's safe to say that teenagers have been experimenting with sex since, well, since there have been teenagers.

And while this experimentation may be a normal part of growing up, the stakes are high. According to this infographic from PublicHealthDegree.com, one in four sexually active teens will contract a sexually transmitted disease this year; every two minutes, three American teens will get pregant. The infographic argues that comprehensive sexual education is the answer. Check it out, and tell us what you think.
