I don't know how this got into a BDSM discussion, but dude - think about it: if masturbation caused a decrease in testosterone, then guys that just have a lot of sex would be hairless guys with man-boobs asking women out with falsetto voices. I mean, really.
As far as your brother learning about sexuality from the Bible, well....he's being indoctrinated to think that a lot of things are wrong and that there is an invisible being in the sky who is watching his every move, inducing guilt in his natural desire to think women are attractive.
This is not to say that porn addiction isn't real, but church certainly isn't the answer. There you will learn that every conundrum that can't be explained will go away if you pray about it. Ask god for help, and he will take away the very desire that he gave you in the first place, right? Personally, I always thought thought that prayer was the last resort for the truly damned.
Science can't offer a complete answer yet as to why people engage in activities that are detrimental to their lives. So Christians will still tell you that "Jesus saves." Hell, I used to drink myself into oblivion regularly and couldn't figure out why. I tried the Jesus pill, and found out that swallowing that delusion made me check my brain at the door, and didn't do a damn thing but turn me into a guilt-ridden, brainwashed, paranoid idiot.
