couple of things already mentioned, first BBS shaves are for the guys who are just starting out, it seems to be a cool thing to say. CCS is what you want, going over the same area with a razor is no good, unless your really good. and with that razor you must be careful. second for a while get you different blades for the Dx, i think its called Pro-Guard, it is a feather blade with some built in protection, Trust Me On This!. third, is been said your using too steep an angle and pressing to hard. i use a Feather all the time while traveling you need to be almost flat on angle with it.
oh you can listen or dont, but any time you have yourself convinced you know it all , you dont, it takes 100 shaves to get proficient. the tugging shows this, your angle and pressure has dulled your blade.
now advice number 4, there are a few guys in your area, look them up and get soem face time, you will be miles ahead
