I have sensitive skin also, and I've found this works the best for me. I find that if I shave right after my morning shower, while the bathroom is still steamy, I get a much smoother shave. Also, do not use hot water. Use luke warm water. I have had almost no skin irritation using these technique. BTW, I use a Gillete Sensor Excel and Gillete foam.
Hope this helps.
