In the nude!
I usually don't waste much time. A vigorous body scrubbing sure, though I am partial to just holding my head under the shower for a while whilst leaning against the wall. Relaxing stuff.
By myself, I wash top to bottom, I use a Dual shampoo/conditioner mix and Axe Sport bodywash (which I used since before the awesome commercials). I usually have to wash my hair twice since my body produces excess oils than most people.
With my girlfriend, which it usually is since her's is more routine than mine since she does her's before she goes to work, we usually wash each other... and stuff.
Chest, arms, armpits, abs, groin, thighs, hair.
Does anyone actually wash their legs? I've always wondered that.
I usually wash my hair first before I wash my body. I start from top to bottom. I usually shave before I get in the shower and then wash off the excess once I get in.
With soap and water?
My mom puts a tarp down on the front lawn. I get naked. I lay on the tarp. My mom sprays me with the hose for a few minutes. She then throwns me a grocery bag with my clothes in it. That is how I shower.
Crutch, hair, crutch, armpits, crutch, upper body, crutch, legs and feet, crutch.
I just go to the strip club and MAKE IT RAIN!
I suppose it's something like this: Hair, left arm, right arm, chest, belly, my back, left leg, left foot, right leg, right foot and then finally the crotch.
Head, Shoulders, Knees and Toes. Knees and Toes.
I step in the water and become purified by righteous water cast upon me by the mighty Poseidon himself oaaaaaaargh it burns
after 15 minutes I'm done.
Hair first then face then from top to bottom. Why would you save your hair and face for last? Then you're just washing the dirt from your hair and face down your already cleaned body, making it dirty again. Wash yourself the same way you wash your car (or should wash your car) top to bottom.
I am adventurous and go for the soap and water function often.
