Is Great Sex Better Than Good Communication?

(blush) right about now because I don't normally bring up too much about sex, but this is a valid question, but I don't know if I will ever find the answer to it.
Sex is a very important part of a relationship, but so is communication. What if you don't get both of them? Would you rather have one over the other? Or could it be possible to ever get both? To me, I would think that communication is the root of the relationship because if you can talk to each other, then you can communicate what you like and don't like, even about sex. What if your partner doesn't like to talk? That's where my problems lied, I think because he did not like to discuss anything. He didn't like talking much. Could that have been our downfall? So, would you rather have a great sex life with your partner even if you don't have good communication? or is having good communication the key to great sex?
