Well...growing is still a thing, but I'm sure you figured that much out on your own. Then there are zits. Which are basically just these gross little lumps you sometimes get on your face. But they aren't permanent or anything. It has something to do with like...the oils in your skin? So as long as you wash your face and stuff you shouldn't get them too bad.

Speaking of your face: facial hair. Well, I guess hair in general. Human males have hair in lots of places. And uh...your balls dropping.

[Most potentially awkward for last. Oh wait...no scratch that. Leaving out awkward random boners, so not even talking about the most awkward one. For now, anyway.]
