First time at the gym locker room :S (Guys)?

Wow do many questions with so little time lol but here goes. A shower is for washing nude..I would not wear a towel...Its not necessary to carry on a conversation while showering...yes take a nude shower and wear flip flops on ur feet so u don't get athethets feet...if u see someone u know just say "hey how's it hangin" lol and if ur comfortable showering with ur dad and friends do it..ur dad certainly knows what u look like...but I'd stay away from the farting part lol and yes clean thouroughly including ur , and hole, just like u do at home. Any more questions?
