Welcome to the club!! That is a really smooth looking shave for your first time I'm impressed! I remember when my head looked all red and angry just like that my first shave was a bit bloody since I cut a ton of heads off (eww i know). I pray that you see the same results myself and others here have seen from shaving.
When you talk about the feeling of being eaten... I completly understand and can still remember exactly what that felt like.
Keep us posted I'm anxious to see if that swelling starts to subside over the next few weeks. Keep it clean and try not to touch lol... We are here for you man feel free to email me directly or post any questions anytime!
