When you are an experienced woman and your partner is not?

I'm with a man 10 years my junior and he has had very little experience as a lover. His first experience was with a hooker a friend of his "gave him" as a birthday present while in Mexico. He's uninterested in foreplay and is a "wham bam thank you ma'am" kinda lover. I've tried teaching him, coaching him, porn, romantic movies and he's just not getting the idea at all. What else can you do for a guy who's a get it in, get it out, and get on with the rest of your life type of lover? I'm about ready to call it quits due to this issue and me feeling like my needs aren't being met, but I hate to because he's a great guy aside from this.
