Recently, since I've been sporting a goatee, I've started only doing one pass when I shave. I've never been one of those guys who goes after a BBS shave, and I'm finding that a single pass is getting me as close as I care to be. It's also been great since I have extremely sensitive skin on the right side of my neck, and reducing the number of passes has virtually eliminated any discomfort I feel immediately after shaving.

Does anyone else only do one pass?
