I NEED ADVICE!💙

My boyfriend and I want to have sex. Neither of us have ever done it but we both feel like we are ready. We know that we shouldn't plan it but it's kind of hard not to when we're always busy so we've planned to do it on prom night (I know, cliché). Please give me some advice/encouragement. I am ready but I'm nervous! I need tips. On making it better for both of us. And I need encouragement because the only thing I'm afraid of other than rejection is the condom breaking. Please just give some tips and pointers to help make my first time not so crappy.
