I am 19 with a fairly thing beard and still relatively (compared to all the 35+ year old guys out there) soft whiskers. I am pretty sure I have sensitive skin, because I usually always have razor burns under my chin and above my lip after shaving using a mach 3. This is one of the many reasons I am switching to straight razor shaving. I am wondering what shave soap or cream would be best for someone like me. Also, what's the most inexpensive way to test new products (college student with no job).

Thanks in advance,
-Brent
