(intimacy/sex mentioned, don't read if it can trigger you or your OCD)

For context I live with my coworkers (2 girls, 2 boys) and I'm always worried about being inappropriate or not being respectful enough (that's one of my OCD obsessions).

Last night I needed to pee and as a male you know what happens when boys need to pee, and basically realised half the way through the bathroom that I had my Johnson partially out of my boxers. Of course I didn't realise it before going out of the room, and as we often changed in the same room I didn't put pants on before leaving my bedroom, but now I can't stop obsessing about how creepy I am and don't know what to think. 

Was I inappropriate? Should I worry? 

Any thought would be appreciated. Thanks and sorry for how weird that was lol
