Is OTHER wrong in the post ? POST : I have five housemates, 2 male and 3 female. I'm male. We are all between 19 and 22 and go to college together but don't really know each other too well.

Anyways I have a female roommate that has a horrible habit of NEVER knocking and assuming people will always lock doors. She opened the bathroom one time while I was showering and yelled at me for not locking the door and then asked to brush her teeth. Another time she opened my fucking bedroom door to ask me a question which is a huge invasion. I regularly see her try to open locked bathroom doors when someone is clearly showering. 

Anyways today I got out of the shower and heard her bedroom door slam, which meant she was coming to the bathroom and definitely wasn't knocking. Anyways I actually forgot to lock the door and thought on the spot "I bet if I stand here nude when she opens the door she'll NEVER not knock again." Anyways I just remained standing naked and she opens the door, her jaw drops and she slams the door. 

After I got out I saw she was waiting in the hallway. She says "You didn't lock the fucking door. I literally saw your penis dude,  not cool." And I said "maybe you should start knocking," and she says "how about you lock the door? You made no effort to cover your penis when I opened the door. You're lucky I'm not reporting you for sexual harassment."

Am I really the asshole here?
