My boyfriend's average-sized penis leaves me unaroused

I've been with my boyfriend for a year and a half now, and I've got to admit, his cock is nothing special. It's just your average size, nothing to get excited about. Don't get me wrong, I love him as a person, but I'm all about the action in the bedroom, and his lackluster package is just not doing it for me. I've tried hinting to him that I'm not completely satisfied, but he just doesn't seem to get it. I've even gone as far as to suggest he gets a bigger one, but he just laughs it off. I'm not being shallow, I just want to feel that intense pleasure that comes with a bigger cock. I know some people might think I'm being unfair, but I'm sure there are others out there who understand my frustration. I want to enjoy sex with my boyfriend, but his average-sized cock is just not cutting it. I hope he'll eventually understand and make an effort to satisfy me.
