Firstly let me say that I never had a problem with any escorts hygiene. I have met a few who were in rather shabby accomodation, which is a bit of a turn off.
Some girls shower between each client and some dont.
I know two who dont, and I do not have a problem.....One will not allow any hand or finger near her pubic area. and the other does massage mainly and is never totally naked.
Obviously many girls who do massage have to shower because they are covered with jelly,or oils etc.
So really it depends on whatever activity the lady indulges in.
Needless to say I hope I never will have such a problem
