Left Handed Side Burn Shaving Problems

Quick Question.

When I shave the right side of my face with my right hand, everything comes out well, I have stubble (no BBS yet) but no hair.

When I shave the left side of my face/sideburn area, the whiskers are not cut. Even after three passes they are still the same length. It is not all of them just a few.

What could I not be doing on my left side that I am doing on my right side?

I try different blade angles but that did not help (really flat and 60 degrees).

Thanks!

I'm guessing it's a technique issue. If you're new to using your left hand for shaving you might not be making enough contact on your face to cut whiskers. I'm really hesitant to use the word pressure here since it shouldn't take much at all. I'd prefer to call it an "unconfident" stroke, if that's even a word lol.
