Is it normal that I'm 15 and can pull my foreskin back a bit but not much?

Hello, I'm 15 and I want to know if it's normal that I can pull my foreskin over penis head when I'm masturbating but not much. Is this normal? Should I pull it over? If so, how can I learn to do it? I was thinking ahead to intercourse later in life. Thanks, help is appreciated.
