Welcome! Stick with it, it will come. I went through a hamburger phase myself. Lots of nicks instead of the skin irritation you describe. When I was starting I just couldn't do a DE shave every day, it was too hard on my face. I used an electric razor between DE shaves just because that was what I had. Looking back, I think this was better than using a cartridge because the electric didn't interfere with the DE techniques I was trying to learn.
Anyway, we're all proud of you that you've decided to stick with it. Keep at it, its worth the effort.
