Am I the only one very particular about my bed?

It irks me a lot when my so will come home from work and lay in bed in his work clothes. I ask him to shower and put on clean clothes before even touching the bed. Bedding is washed every other day. I do not get in my bed before showering either. I have no idea why I’m like this.. im wondering if I am a psycho lmao

Edit: his job includes him going into other people’s homes. I don’t want other people’s germs brought into my bed. My job also includes being in other people’s homes.
