I feel like I can’t satisfy my gf.

Me and my gf have been together for just a couple weeks but we started doing hand stuff before we became official, for me, she was the first person I’ve ever touched in a sexual way, I did receive before but never gave, so I was a bit scared to get into it.

I’m the more feminine one in the relationship and I have nails, salon made ones, and just now she said she doesn’t like me playing with her clit since I’m really hurting her (they aren’t long or sharp but I do understand since it s not the same as natural nails) so I got down on her (also this week was the first time I did this) and everything went well at first until she started shaking and telling me to go faster… but I couldn’t, way too hard for me to go so fast, so I wanted to help her come by doing it with my fingers on her clit trying my best to not touch it with my nails but she said it really hurts, so I kept going with my tongue until she told me to stop.

Then we called it a night (it was already morning but anyways), and after she left (long distance) I said I felt really bad I’m not good at it and I can t even use my fingers, she comforted me and said she really enjoyed it and I did a good job but idk what to believe.

What should I do until the next time I see her? I really want to make her feel good.
