any tips for being intimate with a woman?

met a girl who is a few years older than me. she's been in a few relationships already and has had sex with other woman. i have recently over the last year come to terms with my sexuality so i have yet to be in a relationship with a girl (also, none of my prior situationships have worked out lol). i also feel like i should mention i haven't kissed anyone.

i really like this girl and if the time comes i wouldn't be against sleeping with her. what do i do? i don't want to mess it up cause she's experienced and i'm not. like i know how its supposed to work in theory but for obvious reasons i'm a little nervous. any tips or advice?
