Hey there and welcome to DFS,
Jeffreyba! This is a great group of shaving folks who I'm sure you'll find to be helpful and friendly.
The jawline is tricky because you've got both a curve (for some of us it's a pretty dramatic curve), and the jawbone right there. It's easy to lose the correct angle of your razor when going around that curve, or unintentionally add extra pressure, both of which will lead to irritation. My way of handling the jawline is to pull up on the skin from above, which shifts the skin up to the flat part of my face above the jawline, then shave it while held there. When you release, you'll see you've shaved the area normally covering that tricky jawline area.
The areas at the back of my jawline can still be tricky, so I just take my time there, focus on angle, and use a very light pressure. Generally though, fewer passes over an area is better than more if more means irritation and damaged skin.
A good DE technique takes time, for sure, so don't get too frustrated as you continue to practice. Generally speaking, you'll keep getting better and soon it'll all come together in an excellent shave much more often than not.
