Me(21M) and my girlfriend(21F) doing it for the first time.

Basically me(21M) and my girlfriend (20F) are planning to have sex for the first time and she said that she's scared of getting pregnant so don't want to do vaginal. She said that we can do oral and can try anal, but this is our first time doing it. So what all things I should keep in mind for making it enjoyable for both of us.
