So obviously the general theory is that when I use an alum bar after a shave, and it burns a bit, that my razor is not 100% up to snuff or I am applying too much pressure/angle whilst shaving. My question is the following, however...

Is it possible that my skin is just sensitive to the Alum bar? It burns mildly upon application on my neck, after a shave of course. My neck is and has always been particularly sensitive. I don't ever show any overt signs of burn or irritation, however. I don't get bumps, general redness, or otherwise. Perhaps since I am still new and adjusting this is normal, but I think I am relatively well dialed in. The burn is by no means prolonged or intense, but it is there. I have a pretty good grip on the sharpness of both of my razors, and they seem up to the job as well. Typically this happens in 2 or more passes.

Any thoughts or experiences appreciated. Otherwise I love the bar and the way my skin feels after its application (once the singe passes).
