First kiss help?!?

I know this is going to sound pretty pathetic, but I'm a slow mover! So tonight is going to make the 5th date with this girl I really like. She likes me too, and I apologized to her because I feel like I'm moving pretty slow, but she says she respects me for going slow so she can trust me and understand her feelings for me. We are both in college but this is my first time ever being in a relationship this far with a girl. I'm new to all of this and I'm still trying to figure how things work. I just don't know how about going in for a the kiss. After every date I've walked her up to the door and we kinda stand there and say I've had a really good time and kinda look at each other then usually I get pretty nervous and we just hug. I don't know the steps about how to go for the kiss. Any advice would be great! Thanks everyone!
