You be the judge: should my boyfriend save his post-gym shower for when he gets home?

We go to the gym together, and I believe that even if you shower there, you still need another shower when you get home, because youre not really clean...

I also think theres little point in showering at the gym, taking the tube and sitting on dirty seats, and then going home..

Hes worn those clothes all day, then gone to the gym and travelled home bringing back gym and train germs with him so how can he be clean?..

Id like him to skip the shower at the gym and travel home to shower instead, before changing into his PJs or lounge clothes..

Marek thinks Im being over the top, but the thought of germs from the train in our home grosses me out, as does the idea of him climbing into bed after a quick shower in the gym...
