I just want to nut... the struggle is real
What do you mean by 'nut'? I didn't quite understand.
The feeling of being sexually satisfied by ejaculating.
Well if you really have to do that, then most people would expect you to do it in your own house. If you're home then there's nothing wrong with it.
I can't do it right now, I'm in school! I will be arrested for indecent exposure.
Oh, that makes sense. While it will be difficult you should try thinking about unpleasant things until you don't have to release yourself in that way for now.
