Razor, sounds like you were going too fast and put too much pressure on the blade end and dug in.
Don't give up on the HB my man.
I say stick with that routine, it sounds like what I have been doing for a while myself.
I bring the razor that's currently in my rotation into the shower. After I'm done with the HB, I do a quick scraping all around to get any or all spots I may have missed.
Let me tell you I have been getting the smoothest, slick noggin' since I started shaving.
Works well for me, and if you have patience and give it time, you will be able to make passes with the HB that are almost horizontal. Especially behind the ears.
Well, heal up quick and try it again, this time go very gently. Let me know how it goes.
