Does ocd make a person hyper attentive about the environment?

I have ocd(currently undiagnosed due to my circumstances at home but I definitely have it) and I feel like it's at its peak because I can't sit in the chairs in my own home or do anything else for that matter.

Anyway, nowadays I'm extremely aware about the environment. And about the question, I'm not saying it in a positive way. I feel like my attention to my environment ans surrounding stops me from touching anything in my home because my ocd believes that it's contaminated. Is this normal?

PS English isn't my first language but I've tried my best.
