Yo guys I need some help with this. Do you ask someone to be your valentines before valentines day or do you ask them on valentines day?

What kind of question is that? You asked them before Valentine's Day so they know that you're their Valentine so they expect something out of you. But if you want to be mysterious and stuff, you can do it.

Cameron, it should be done before Valentine's Day, not on Valentine's Day.

I'll do it, I'll do it, I'll be your Valentine. I know, I know, no worries.
