No, no; while Christians may have Jesus watching, I think only the Catholics want grandma in the room. (See "communion of saints" and Luther)
The weird thing is, he doesn't need to watch as he already knew what you were going to do and when and why and how you will do it in the future too.
Weirder still is trying to figure out what that means in regards to free will. If Jesus knew that tomorrow you will do nasty things to those inanimate objects while thinking about kinky shit for sexual gratification, did you really have a choice in the matter? (See https://plato.stanford.edu/entries/free-will-foreknowledge/ )
Which means, when you get down to it, Jesus wanted you to do that kinky shit. Some priest probably steered you wrong on the lesson of Onan.
