In hotel and there is a communal pool change room for each sex. In the women's one day when I was drying my hair I saw a woman stark naked with her leg up on the bench applying cream to her vulva/labia. I wasn't staring at her I just glanced up as I head the door from pool open and was checking if it was my friend.
There are private changing cubicles/many toilets/shower cubicles less than 5 foot away from her.
I'm not offended I'm just confused why you'd do it in full view of everyone. Am I being a prude? I don't often go to pools/gyms with communal changing. So maybe I am out of touch with the norm? My local one is mixed sex and all single cubicles.
