How do I stay normal near girls?

I am 20M and I feel like I act differently near girls and not in a good way. I am mostly nervous near them and frankly, I hate that.

I literally have zero problems with hanging out with guys doesn’t matter if I’m meeting them for the first time or not. But in case of girls, I get nervous, or shy or something… I don’t really know. I just act not-normally.

I wanna be able to talk to any girl normally and not have to think a million times before any action. I have almost no experience with women as you can probably guess which I think is part of the problem but I cannot just magically make that problem disappear. What should I do?
