Pee is sterile, so all you need to do is make sure your penis is dry after each time you pee. If you are going to have sex you should make sure that your penis has been washed and dried first and if you are not trying to have a baby with your life partner, you should always use a condom.
You should clean it everyday that you use it.

Although this question doesn't make sense, I'll answer it anyway toy best understanding. You should only put your penis in clean places. Ex. Make sure the girls vagina is clean (if it isn't it'll smell like fish)
I clean my pennis in the shower.
Keeping penis clean is very important. 1.) Gently pull the foreskin back. 2.) Rinse with warm water only. Soap under the foreskin can cause irritation and swelling. 3.) Pull the foreskin back in place over the head of your penis. Circumcised men can directly use warm water and soap and clean it carefully.
