Is my son gay? what should i do?

the other day i was browsing my computer and i noticed homosexual pornography in my browsing history, i was taken aback to say the least, i disregarded it, but just yesterday, i walked in on my son masturbating to an episode of GLEE. I'm a proud Texan that lives in a republican household with strong moral fiber, so i don't know what to do. We restricted his internet access and he is grounded for an indeterminable amount of time. My wife suggested bible school (pray away the gay), but im thinking military school, they will beat some sense into him. Please help me i'm at a loss.
