Doggy style

So I absolutely love my bf and I don't care that he's considered 'small'. He's 4 inches, but it's not like pencil dick thickness, the thickness is average. Anyway, I know he loves doggy, mostly cause he gets to look at my ass. BUT it does absolutely nothing for me. I can hardly feel it... do any of you ladies have this experience? It feels good in almost every other position btw.
