Well back when I shaved (trimming the beard is so much easier), I always did it before I showered. I use this face wash stuff in the shower, and I guess it leaves a little residue on the skin, because when I used my shaving gel after I washed my face, it got all sticky and gross. And it made shaving impossible. So not only was I not able to shave, but my face was all sticky. So...yeah, that's something I like to avoid.
