Boredom sex?

Whenever my boyfriend gets bored he wants to have sex... that's a lot lately for some reason, usually I am in either way because I love it.. but lately I haven't been feeling good and he's been bothering me about sex for a couple days, but it's only when he's bored, like if he's playing games he doesn't pay attention to anything else other then that but then when I get on all that's on his mind is sex. I've just got no interest in it lately and that's not normal. How should I go about this situation? He also says I need to get better at rolling my hips while being on top.. any advice would be helpful. No negative comments please? Just a little rant.
