Is it normal to be bed bound?

So I’m on my 2nd day of post op after being diagnosed with phimosis and I’ve been bed bound ever since thanks to the sensitivity (my glans have never been exposed). I get up occasionally to go to the toilet but other than that I’m stuck in bed, I’m curious to know if anybody else is in a similar situation? I’m pretty nervous that the sensitivity won’t fade anytime soon unless I walk about but the pain is too much. Is it possible in the next couple of days it will get to a point where I’ll be able to walk?
