Well, deep-throating, like anal penetration, is just another one of those things that floats some people's boats and turns others off, it doesn't really bug me (I'm quite partial to a bit of a gag myself, it pushes some lovely power game buttons for me), but I agree that like their buttsecks, their blowjobs can be a bit tired and clichéd as well. For God's sake use your teeth for once for a laugh, make him squeak. Or something.
