I'm thinking of watching videos on facebook to pass the time. Do you think that's a good way to spend my time?
Why do you want to watch Facebook videos?
I don't have a reason yet, but I think I also want to watch while thinking about my classmate and having sex with them while snuggling.
You can watch and do whatever you want in private, but it's a little creepy to let out such thoughts in public. They should be kept in your private mind, because if you tell people, they might get really creeped or weirded out from you.
I see, does that mean I might have leaked out my sexual orientation?
You shouldn't share things like that online. It's best to keep that part of your life private.
