Try Aero Kroil instead of PB Blaster, or try a 50/50 mixture of acetone and transmission fluid. A long, six-point box end wrench will work well to unscrew the sensor. Then use one of these to clean up the threads in the HO2S bung.
If you get 2 to 3 full turns (360 degrees * 2 to 3) before you hit resistance, you probably didn't crossthread them, you probably hit some crud in the threads.
http://amzn.com/B0009OMYCO is a handy tool to clean up the spark plug threads before you thread the plug in, but you have to be very careful not to cross thread that tool. Also, have the end covered in grease when you use it, to capture all the crud that you get out of the threads. The best way to use it is to turn it backwards (lefty loosey) until it clicks straight, then start turning it in. That works for both the spark plugs and the thread chaser.
