Much less pressure is key. I can actually use a fair amount of pressure on the N-S strokes. I use a little less on the E-W pass and then as little as possible on the true ATG pass where I'm really going with my face map. For instance, those little swirly places most folks on the sides of their neck, I am going sideways with them, but with no pressure it never gives me irritation.
Don't be in too much of a hurry, impatience is one of the biggest problems around here. As is razor rotation. I suggest you have one razor only and shave with it daily for at least 6-8 weeks before trying to flit from razor to razor. And stick with a couple of known good lather products like a TOBS cream, Tabac or a RazoRock soap for a while. Great lather helps in the ATG pass. I was getting decent results right out of the gate, but I think it took me about 3 months before I was REALLY expertly comfortable and getting a daily DFS/BBS shave without any irritation at all. Ever. Take your time. It will come.
