I shave with a double edge razor and don't usually do a clean shave, just clean up the edges of my facial hair, but yeah I don't usually use that stuff either. It's mostly not required. When I do do a clean shave I do use shave soap, but it's also nicer quality than the cream or gel you'd buy in a store, with lanolin, tallow, and/or other oils added. It's slightly more effort but if I'm going through the effort of a clean shave anyway I like to enjoy it.

ironically i prefer shaving in the shower without cream, it's almost like women figured out something mildly useful in that regard...
