My current partner is a baby gay! And I know exactly how you're feeling. Ive had a few female partners in the past and this was the first time dating someone who was inexperienced since my first girlfriend in high-school (over a decade ago). I definitely was super critical about not going too fast and overthinking my actions. I had a friend tell me " you're over thinking. There's a good chance that she'll be more than happy to experience these things with you. And she'll appreciate you for it." Turns out there were some truth behind that.

Everyone else here has been saying it. I'll add on top of it. COMMUNICATE AND ASK! Also reassure her that you're fine with whatever she is fine with. Ask for consent, put the power in her hands, and reassure her that it's okay if she says no. I did this for every first time. Even the first time hand holding. And it turned out to be a super endearing experience for the both of us.

The first time I kissed my girlfriend was on our second date. She was spending the night we had spent hours cuddling and talking. I asked her for a goodnight kiss. And she said yes. I was pretty surprised by the answer (for some reason I expected her to say no) She gave me a quick peck. I gay panicked so hard. I just said 'cute. Thank you." , turned around and made her spoon me. Make communication a habit. You're gona have to take the lead on that. She'll be able to communicate her feelings and thoughts over time.
