I mean, depends on the household? Like if you close the doors it just telegraphs to others that you wanna do something "nasty" aka something you don't want others to see. So like jorking with unlocked doors but in a way that even if someone comes in they wont instantly see your jorking target if you will, and thus not know instantly that you were jorking is just less risk than jorking with closed doors, where they will know instantly that you were doing just that

.
Question is - whats worse - them knowing for sure you jorked each time they tried entering your room and found out the doors locked, or small chance that they would see you with the shlong in your hand when they entered your room when you didn't lock the door and jorked. Or maybe the thrill of being found out would add to the experience?
