Finally achieved ATG without irritation
This morning as I was shaving before leaving for work, I had a bit of an epiphany and was able to do a full ATG pass on my neck without causing any razor burn. Before this morning, I had resigned myself to the idea that ATG was never going to happen on my neck. Every attempt before had met with quite harsh razor burn and ingrown hairs. However, this morning I finally figured out what it means to use no pressure while shaving, and I think my whole shave will benefit.
It's taken me nearly three months to get to this point with my shaves, and I just wanted to post this so that other frustrated noobs can see that things do get better. I had a hard time getting my bearings once starting down the straight-shaving path, and with the initial obstacles out of the way I foresee things continuing to get better and better.
