"We've been together for a year and recently he's started talking to me while we're intimate. At first it was everyday stuff like what he wants for dinner but then essentially he began ranting. Do you know how hard it is to climax while listening to someone talk about how many bands have produced 'disappointing second albums'? I don't know if I can go on like this."
This woman is so against talking that she can't talk.
If you give the other person the impression that you like something that person is doing during sex, they'll probably do more of it. At this point, she's been so withholding of communication that he should find her quite unappealing if she finally does speak up. Writing a letter to an advice columnist instead of talking to him? She thinks he's being unsexy, but she's unsexier. And the 2 of them are unsexy in completely opposite ways. But she's being unfair to him, while he is trying to please her, continuing with the thing that she's pretending to like. Plus, you've got to read between the lines and see that this man has great sexual endurance. He's talking about all manner of things because he's going on for — what? — hours. And all she's really thinking is: When will this be over? And by "over" all she even means is: When will my body do that orgasm thing in spite of this guy?
Back off, lady, and let somebody who appreciates fuck talking have him.
