What I don't understand is....

WHY is it? When we ask you guys to feel free to freshen up, and you kindly hop in the shower, that you only wash the front side and completely neglect the backside?????? Even though we may not go there, your asses do smell! It's repulsive, to be honest.

My advice to ALL....wash not only your front but BACKSIDE TOO! And help yourself to the mouthwash while you at it! It is GREATLY appreciated!!!!

My suggestions are foundated from my own personality type and belief systems
I am a compassionate woman...
So, with that said...
I would avoid putting a damper on the other persons' libido
I would not attempt resolve this situation, in a course manner or make a funny peeeeeeeeeeeeeew faces
That would ruin the whole experience in entirety
And in my opinion it would be mean to say..
"Hey your a$$ smells...You need to wash it!!"

Possibly suggest offering a special sudsy erotic shampoo??
Or maybe a joint venture to the shower....
OR just grin and bear it!
This business involves intimacy...
Like any business there are ups and possibly smelly downs
Intelligent tact and resourceful approaches do prevail!
Good Luck!
