I shower when I need it, in summer that's usually more often. In winter on a day that I don't exercise - I most likely don't shower, just a quick wipe with a damp cloth of face and crotch (in that order!) You skin will love you for it. Usually at the end of a day.
Think outside the box with your whole life. Scrub your skin vigorously everyday, right up there with eat your grains if you ask me, just because it's the social norm, conventional wisdom doesn't make it right.
But on the other hand, don't be a stinker like Steve Jobs was in his youth (according to his biography, the dude wreaked from not bathing hardly at all back then).
Over bathing makes you stink more not less. More not less, it's counterintuitive. Leave your skin be and find an equilibrium.
IF you have sleeping issues, showering before bed can affect that by waking you up, though some find a hot soak in a bath is very useful for its soporific qualities.
In the morning, personally I just don't have time to shower on work days, unless I got up 10 mins earlier, I would rather have 10 mins of extra sleep.
this is an interesting read. I have quoted the section on over washing.

From a young age, we're taught that
the daily use of a hot shower, copious
amounts of soap and a scratchy
washcloth are necessary to rid
ourselves of dangerous microorganisms
and the putrid smell of human skin.
And if you aren't squeaky-clean, you
can forget about dating, career
advancement and the promise of a
future that doesn't involve dying
alone in a den of your own filth.
As it turns out, showering or bathing
daily, while it may make us more
socially acceptable, wreaks havoc on
something hilariously called the horny
layer. Hot water, soap and abrasive
surfaces strip off the horny layer,
exposing living cells to the elements.
And although we've just used the words
"strip," "exposing" and "horny" in the
same sentence, we assure you that this
is not the making of a sexy situation.
On the contrary, damaging this
protective layer of skin makes us more
susceptible to disease.
Before recent modern conveniences,
people bathed less often, and
frequently in the same water. Even
nowadays, showering doesn't kill
bacteria or other microorganisms,
though it does move them around. A
colony of bacteria living on your
shower wall might move to your leg; a
colony from your leg might move to
your head; a colony from your groin
might even take up residence on your
hands. For this reason, surgeons in
many hospitals are not allowed to
shower right before operating.
Studies have shown that there are no
measurable differences in the number
of microorganism colonies a person is
host to regardless of how frequently
that person showers. Of course, using
antibacterial soaps can kill
microorganisms, though in an effort
not to create too many super bacteria,
medical experts generally recommend
not using these soaps daily.
So how the hell are we meant to do it?
The most important thing to do to keep
the skin healthy is to preserve the
horny layer. There's no magic number
of showers each week, though it's
generally agreed that the number would
fall somewhat shy of seven. Skipping
showers, or, if you'd like a fancy
French term, celebrating sans douche
days, gives your skin time to repair
some of the damage that the last
shower caused.
When you shower, use warm or cool
water and a mild soap (if at all), and
rehydrate the horny layer by rubbing
on some moisturizer afterward. Better
yet, convince an attractive friend to
help with this. Once you've cleaned
up, you'll want to make sure you air
dry. Ignore protesting roommates or
family members and remind them, as
you're drip-drying at the breakfast
table, that they should be grateful
you're showering only a couple of
times a week.
