Improving Oral

My boyfriend and I have been dating for almost a year now && a couple months ago, he took my virginity. My boyfriend is 21 & I'm 18, so of course I'm not his first. We are getting to the point where oral plays a VERY BIG part in our intercourse, because I know he likes it && I'm very big on pleasing him(because he pleases me) So I want to know some helpful ways to improve my oral sex skills. Ladies???
