How can i make sex as painless as possible for my girlfriend who is a virgin?

My girlfriend and i are thinking that we might want to have sex soon we’ve been dating for over a year and are both a few years over the age of consent.

My question is that, yeah i know it’s going to hurt her, i was hoping for tips or suggestions that will help it not be as bad for her. Things i can do, things she can do, pretty much anything that anyone can suggest. How can i make it as painless as it can be for her?
