Something Has Come Up

As a teacher of high school emotionally disabled students, you run across a lot of... odd stuff. And I wouldn't dare to make or poke fun at them to the world because I would seem crass and uncaring. But I do to thier faces. Because it often times helps us all cope with... the weird stuff.
For example, one of my students has Pica. Which means he will eat just about anything. Like tacks, or staples or his plastic binder. Loan him a pen? Forget about it. Give him paper? It's gone. He gives a whole new meaning to the saying "I ate my homework". Oh wait... that's dog.
But I love this kid, and we joke about his eating of "stuff" and we laugh together, because what else are you suppsed to do? And when we played a trick on the other students and had him jump up and down and had the teaching aide shake a box of paper clips so it seemed like all the metal was jangling in his tummy, it went down in history as one of our favorite moments in all of time. Because he can't control the Pica and so he must learn to laugh about it. Or else he will become a murderer just because he can't quit sucking on his Algebra book.
At any rate, one thing about most high school boys that is universal is the onset of puberty. And all of the "things" that "grow" from it.
And in my classroom I have had my fair share of what some guys refer to as the NRB ( No Reason Boner ) and believe me when I say I do my best to turn a blind eye.
But at the moment I have a student that tends to be... "going through puberty without control" and it's making me feel a little on the hinky side. Becuase I can tell a kid he needs to shower when he really stinks. I can tell a girl that her shirt reveals too much boob fat and needs to cover herself. I can even tell the pica eater to "stay away from my paper clips"... but I dont' dare confront the boy with the... risen appendage... with anything.
So this boy keeps "getting himself into this situation" and then standing in the middle of the room by the half-wall room divider. Hiding "certain parts" of his body. Which is inappropriate- as in CLASS IS STARTING. And I am GIVING A LESSON. But I just can't say it. Because I don't really know what it's like. And frankly, I don't want to know anything more about it.
I asked my husband about it and he informed that this is sorta normal at certain ages. And the wearing of baggy pants might help. And that I should leave him alone.
But when your classroom is all about structure and then the Boner Boy is over against the half-wall rubbing it out, what is the female teacher to do... when already the boy is ostracized for a myriad of other eccentricities. Because honestly, at this point in the game, if you made it into my classroom? You are most likely already on the "outside", if you will. So the "group" confrontation would be beyond humiliation. And there sure as hell ain't going to be no "private confrontation" between me and a boy and his... grody thingy.
So I am hoping this phase passes by sooner rather than later.
