My BF has a rather irritating habit of coming the bathroom when I'm in the shower and I really don't like it. I don't think there's anything sexual about it (honestly!), he just doesn't seem to think it's a big deal if he wants to come in and talk to me while I'm washing my hair or whatever.
I've told him I don't appreciate being walked in on and would actually rather have the time to myself. He thought this was strange and said 'it's not like I've never seen you naked before' 
but has reluctantly agreed not to keep walking in on me.
So today, rather than bursting in as usual, he was knocking on the door. I could hear he was saying something but couldn't make out the words over the sound of the water and the music I had on. Figuring it must be something important as we'd only just had a conversation about how I prefer not to be bothered while showering, I got out of the shower (conditioner still on), wrapped myself in a towel and traipsed across to the door (leaving a trail of water) to see what he wanted.
The message which he'd found so vital to relay to me was that the pizza he'd put in for lunch would be ready in ten minutes 
He says I'm ungrateful because he only wanted to let me know so it wouldn't get cold. I think he should have waited until I was out the shower to tell me lunch was ready!
AIBU to be annoyed and to wish I could have just fifteen minutes of privacy?! Does anyone else's partner do this?
