If the bathroom steams up after the shower, make sure if you have an exhaust fan to use it or keep the windows and door open a crack. Also you may want to consider taking cooler showers. If you are worried about the skin swelling cool - cold water actually tightens the skin. I use cold water for all my shaves, I find it leaves me with less irritation as my skin tends to be more sensitive. Well that's what works for me and with straight shaving it's all in what is best for you and your shave. Happy shaving.
