when i know i am going
i shower before i leave the house
i can make sure i am squeaky clean
then i leave for my session
and rinse off at the spa
then rinse off again after the session while at the spa
you sweat from your head so yes, wash your head and face
same here, shower top to bottom at home, shave (yes-balls also), light rinse there if I got a bit hot on the way. I usually wear casual clothes that I’m going to wash anyway so don’t often shower until bed time. I do bring my own soap in case, which is the same as I use at home for consistent smell around the house.
