Face, and in this case neck prep is essential. Try using very very warm water and massaging your neck to get the hairs to lift up as much as possible.
Go really slow and really gentle if your neck curves you need to keep constant blade angle.
One thing that has helped me is to get my neck as flat as possible. I managed this by turning my face to the side and lowering my chin until it touches my chest.
Now you have a flat area to shave. It makes it much easier while you are learning to follow the curvature of your neck with constant and proper blade angle.
Hope this helps
Enjoy your shave,
