My boyfriend can't finger me well, but i dont know how to either...tips?

My bf tried fingering me today and at first it was pleasureable, but then he got so rough and obviously i was making noise cuz it hurt. I tried telling him how I didn't enjoy all that much, but he is convinced my noise and how wet I was means I enjoyed it... and that I came. How do I convince him otherwise, and how do I finger?
