A few thoughts. Less number of blades is better. No more than 3! It took my head about a month to get conditioned to shaving, especially against the grain. I would suggest using a foil type electric shaver, and then switch to a blade every few days. I found the Schick Extreme 3 disposable works great.After you get really good at shaving, try the double edge again, but only when you have plenty of time to take it slow. Hang in there, it takes time to find a routine that works for you.
I shave with a foil shaver these days on my dome. I may go back to a razor but I am quite happy shaving this way for now
