Mmasturbate for first time

I have masturbated in previous years I didn't finger myself only try humped because I could never find "my hole" this time I did and I didn't find pleasure in it. It was uncomfortable and slightly painful. Is it supost to feel like that your first time. I still feel slightly uncomfortable it's been about 20 minutes. Am I doing something wrong? What is it supost to feel like. Idk what to do tbh
