Sexual help

My boyfriend always jokes around and calls me a starfish he brushes it off as only joking but I know I am in bed and I know he gets bored and it frustrates him I kinda just lay there during sex and he doesn't get any pleasure from missionary for some reason which is all we do because I'm to nervous I don't know how to over come my fear I suck his dick and give him handjobs but that's the only time he gets to cum where as I get a lot more pleasure I know what to do I just can't overcome my stupid fear 😩😩
