Do women actually enjoy sex?

I'm asking because I don't know if it's true that women don't enjoy it, or if they do, or if they just enjoy the emotional aspects of sex. I've had a hard time finding any real sources to confirm or deny it. It seems that every time this comes up, it's usually something on Chambers or something that was posted 5 years ago. I'm not sure how to go about looking for real sources, so I thought I'd ask here.
