A lot of us have teen siblings, nieces or nephews or kids. I've got two younger sisters that are barely out of their teens at 20 and 22. And if you're anything like me, you might be worried about what they're doing. My favorite thing to do is know what they're doing at all times.

The CDC released new numbers about teens and sex. The finding? That 40 percent of American teens were sexually active a few years ago in 2017.

According to researchers doing the report:

"Understanding these patterns and trends in sexual activity and contraceptive use can help provide context for the declines that have been seen in the U.S. birth and pregnancy rates for teenagers since the early 1990s."

From 2015-17: 42 percent of female teens and 38 percent of male teens reported being sexually active.

I'm not saying this is good or bad- obviously everyone needs to do what is right for them! I'll be hitting this in Trending 208 in the morning- and 40% is probably higher than I would've imagined, but knowledge is power! Do with it what you will.
