I shower around 4-7 times a week. Mostly 5 or 6 times. The climate where I live is quite chilly, at least at the moment.

In the evening every other day ideally, I forget sometimes though.

i would think about it if i would live in a country where "wasting water" would be a problem but it makes not really sense in germany to think about it. 80% of the water we could use without any problem in germany is untapped.

I usually shower every day. Sometimes I get too lazy on Friday, though. (If I don't take one Friday night, I take it Saturday morning and sometimes Saturday night, too.)

My hair feels disgusting (in my opinion) if I skip a day. I also hate not feeling clean. I live in Florida, so it's quite humid. 

Do 14 year old's take showers by themselves?

Yes. Unless you're on the football team or something, then you take a shower with several other people. Kind of awkward.

2 to 3 times a week, im not a filthy slob, I don't need to shower so damn often

I love your honesty! :) And can remember that when I was a kid it was very like this.

You must be the batman to his bane.

I live in the Mid-Atlantic region so once a day in the winter months and twice a day in the summer months.
