If you ask a guy what his favorite body part is, chances are you already know which one he’s going to pick. But while some guys are very open about their prized penises, there are plenty of things they won’t tell you about them.

Yes, guys have their secrets, too, especially when it comes to their johnsons. Check out the 10 secrets guys won’t tell you about their willies below. You’ll never be able to look at your guy, or his weiner, the same way again!

1. It’s Manscaped

Even if he tells you he’s all natural down there, trust me, he’s not. He’s been trimming, shaping, and shaving to ensure his favorite body part looks its best. Think of it this way, homeowners who are proud of their house landscape their yards and gardens so their home looks its best.

So him doing a bit of manscaping is simply “mowing the lawn”…

2. It Twitches

He can kind of make it twitch and move without using his hands. No crazy spins or dips or anything, but yeah, it moves. (He’ll mainly do this alone in front of a mirror.)

3. He’s Definitely Messed Around With It

While it may not move too much on its own, every guy has totally messed around with his shlong to see how much it CAN move. I’m talking helicoptering in the mirror, tucking and pulling to make a fleshy slingshot and more. Oh, boys and their toys!
