@mikey642, this is a "known issue" for many people, nothing unique, so don't worry, you'll get there!The problem area is the bits that lead from my Adams apple towards my ears. Because I can’t get the angle right on these areas, I end up doing numerous passes to reduce the beard, which is causing irritation, coupled with my angle probably being too steep.
The most simple way of combating it, is stretching your skin sideways, so that the skin covering the Adam's apple gets pulled left/right in an effort to form a flatt(er) surface.
Watch GFB demonstrate this magnificently in the video below. Your issue with Adam's apple starts at around 1:45, but I'd watch the entire clip, it's invaluable.
