I understand all of that completely. The thing with me is that, I shower excessively because I feel that, if I dont wash properly, I will be judged, as people would look upon me as scruffy and lazy. However, in the army, in a situation you described, I would be justifiably dirty, and so would everyone else, so it wouldn't bother me.
Can I ask, entirely out of curiosity, hypothetically, what would happen if I did take excessively long in the shower? Also, how long are you allowed?
btw, thanks for talking to me about this, I really do appreciate it.
