I love Modern Family. It is witty and I can often connect with many of the characters. I was less bothered that they chose to do an episode about a seventeen year old having had sex, and more concerned that it was presented as normal behavior for that age. I don't believe that every high school senior is out there having sex. Nor do I believe that they are ready to. Now, prime-time TV is reinforcing the idea that 17 or 18 is the appropriate age to have sex.
Maybe this is just protective dad writing. But are we really ready as a society to put an age on when it is okay to have sex? Emotional security is definitely something to consider. Many of our youth look at sex as simply a physical work-out. They have removed the emotional connection from the act, making it even more depersonalized. Who in the media, or even in society is reminding our children that not only isn't everybody doing it, but it is okay to wait?
