I've been DE shaving for about 2 months and have been doing really well lately. My lower neck is the only trouble area. I shave XTG on my face because it gives me the BBS shave. I shave ATG on jawline and the top part of my neck. My lower neck grows from S to N, unlike any other part of my face. Shaving XTG in both directions leaves a lot of stubble. Even diagonal passes leave stubble behind. I can't go ATG without bleeding and major discomfort. I don't care to have BBS on my lower neck but I'm not even getting a CCS on the lower neck. I need some help on getting closer here. Any tips for me?
