You say "he's relaxed, I'm relaxed", but clearly he isn't.
All too often guys focus on the girl as there's such stigma attached to ensuring she enjoys it that he holds back himself to ensure he satisfies her. You say you are getting all the pleasure, so at least his techniques are working for you. If you can manage it without it hurting, try going for longer, or maybe once you've got what you want, try using your hands on him. Failing that, suggest that you two m********* in front of each other and you can learn how he likes it done. Also for almost all guys it is a huge turn on to see their ff enjoying herself, so even though you are enjoying it, so it's not faking as such, slightly exaggerate your enjoyment (be a bit vocal) - it will spur him on.
I have never c*** from sex and wish to god that my ex would have tried to accommodate a few routine changes into our sex life.
