I shower first, making sure to make the water as hot as I can stand it at the end. I rub my face and neck with the hot water to soften the beard.
When I hop out of the shower, I get in my robe, put a dot of prorasso on my palm and rub it up between my hands, and apply directly to the place I'm going to shave.
Then, with a nice clean sharp blade, I shave with the grain, half against, and then against. It takes me about a minute to shave and then I'm done. If I want to save my blades, I take an alcohol pad, pull out the blade, clean with alcohol, and reassemble my razor.
I typically get 5-10 shaves out of a blade that way. One ten cent blade can last me a month easily, and I've given up on using a brush of any kind.
I think the key is to saturate your beard with hot soapy water, make sure to do that last in the shower, and then go directly to dry yourself off and then shave.
Maybe you have access to alcohol pads, maybe not. That's what I do.
I typically shave several hours before work or social engagements so I can use a styptic stick to stop any bleeding from showing on the collar of my undershirt.
My favorite soap is Dr. Bronner's Magic Peppermint soap in a Dawn foamer. This has allowed me to use one gallon of soap for over two years, I cannot calculate the savings this has given me.
Best wishes.
