A day in my opinion. I like it when the guy I am dating showers everyday. Some people can get away with every second day, but don't expect any action if things aren't squeeky clean.
Over 24 hours. I like boys to be clean and fresh. Besides, it's not that much work. You don't have to wash and condition long hair like most girls do.
I guy starting at the teenage year should start showering everyday.....
The longest you should probably be every other day but....... EWW
showering daily (if possible) is the best thing
people should shower once a day at the minimum.
A guy should shower once a day
I agree with this.
