This is embarassing to admit, but I'm 20 years old and I've never used gym showers before. The thing is, I don't have time to shower at home, so I have to use the showers. And the showers are always full of people. I know most of you guys will say too "just act normal" and "it's not a big deal", but I get really anxious and nervous in front of other people. Any tips or suggestions?
