Ok girls, I’m gonna let you in on a little secret: there’s a lot you don’t know about teen guys. What’s more, the thought of you knowing some of these secrets strike most teen boys with a bolt of fear. With that in mind, we’re going to tell you anyway. Here are the 5 things that (most) teen boys don’t want you to know:

1. They’re Not as Cool and Casual as They Act

While every once and a while you’ll meet a guy who’s just effortlessly cool and confident, the vast majority of teen boys aren’t. That casual “I-don’t-care” attitude? Usually all an act.

2. They Even Get Emotional Sometimes

Think boys don’t cry? Think again. But knowing that you might know about it is some guys biggest fear.

3. They’re Pretty Gross in Private

Guys are gross right? Sure, but do you know the extent of it? They wear the same clothes for weeks before washing them, eat their boogers in private and smell their own farts. Don’t say I didn’t warn ya.

4. They Secretly Like Your Favorite Movies

Say you’re sitting down with your boyfriend or one of your guy friends to watch a chick flick. He’s probably going to whine about having to watch it with you, but it’s all an act. He secretly loves watching those movies.

5. They Often Pretend to Know Things

Why does it seem like some guys know everything about anything? It’s simple. Because they’re lying to seem smart. If you ask them a question that they don’t know, they’ll come up with an answer, it just might not be factual.
