Help! I can't have orgasms on sex

Hello! I've beer wondering if the way I learned to masturbate is the reason why I can't have orgasms while having sex.. I started to masturbate at the age of like 11 years and I lay on my belly and with my clothes on and I rub my clit with the palm of my hand and that's how I do it. Maybe by doing that my clit doesn't like to be rubbed without clothes or something and that's why I can't have orgasms with my couple or that's what I think...
I'm 19 and I've been for more that a year with my boyfriend if this says something to you.
Help!!! Any advice please???
