I'm still just trying to reason out how, even with his 'training', Clark was able to shoot his wad and not rupture every organ in Lois' body and blow off the top of her skull. I mean, the guy can't figure out the disciplines of flight, how the **** could he have THAT kind of control? Can you imagine if he used super-speed while doing her?
I guess he can control all of his powers, except flight. It's all in his head after all.
