Jleeg, I have been shaving for about 5 days now and have the exact same issues as you are describing, irritation under the corners of the mouth. I think because you and I are coming from a DE background we are expecting a level of closeness from our straights that just can't be had in a short time. I am doing the same as you, attacking my face with as many passess and touch ups as needed to get BBS, but as you have indicated the ole Alum block does not lie, too much metal, thus irritation.

I'm really trying to lessen up on the pressure, it really is a learned art. With the DE all you really need to worry about it blade ange which is easy with little practice and pressure which is also easy. I find with a DE you place th blade on your face and the handle faces down, therefore your motions are to pull down to cut the beard. With the straight you hold the blade higher and have to push the blade down, I'm struggling with this, but it will come. Glad to hear there are other people who did not have the best shave of their lives right from their first shave.
