Forgot to mention, Ocelot is a Dermatologist and he recommended Aveeno Theraputic Shaving Cream. In a can, which in this case is immaterial, as it works quite well any time I'm coming up with skin sensitive irritated shaves. I use it for a day or two till the irritation goes away and I'm free to play with my soaps/creams again.
And before I forget again, my children are of the Jewish/Irish(with a little Danish thrown in) combination. One son does complain about similar conditions as yours. I had him switch to a DE and Aveeno and haven't heard any complaints from him as yet. And believe me, you don't have to be Irish to have sensitive skin. My Jewish/Polish red haired Mother came, as she would put it, "From beyond the Pale" was cautioned to stay out of the Sun as much as possible and I inherited that skin sensitive trait.
