Oral sex

I give my husband Head all the time. I honestly love it. It pleases him and I love to pleade him. I have gotton oral from him maybe 10 times since we have been married and some of thoes times he doeant even let me finish. He just gets excited and we have sex. I want it more but I don't want to make him do anything. Any advice? I love it. He does great and I always cum. So idk what the big deal is.
