More like latent homosexuality. The fussy, anal-retentive male is usually fighting an inner battle between what he wants to be and what he believes to be right. In order to convince himself that he's really straight he goes out of his way to follow all the rules, even to the point of absurdity. These are not pleasant people to deal with.
Part of it is cultural as well. For example, if you have more than an ounce of German blood in you, then after you hit your mid-twenties a disorganized room will likely offend your sense of “ordentlich”.
