do I masturbate weird????

Ever since I was pretty young (12 was the earliest) I've wanted to masturbate. So how I did it would be I'd place a blanket or something between my legs and hold it steady and then I'd grind on it. Is that weird? Now I'm 17 and I've tried to stimulate my clit and finger myself but it doesn't work as effectively as the grinding situation. I just feel like it's a weird way to masturbate.
