well my usual procedure for when i go for a shower is what i call the three s`s
stands for-SHIT,SHOWER, SHAVE!
so normally (for me!) yer piss comes while you crap lol then jump in the shower which minimizes the possibility of needing a pish in the shower and pissin down yer leg in the shower and feelin mingin,then out of the shower which the steam has made yer stubble soft enuff to shave without it feeling like your tearing the hair out your face instead of shaving it!!!
the 3 s`s rock, you feel like a new man afterwards!!
