Do you think there is Sex in heaven?

Well, I was just sitting around thinking about sex and then I wondered is there sex in heaven? So obviously we do not have the need to reproduce in heaven or the necessary equipment to do so. But it seems like if we are created in gods image, then there must be some kind of sexuality in heaven since we have sexuality naturally. Maybe just not as we think of it now. After all, god loves us? Someone could argue that those two examples imply something. So what do you guys think? Here is a link I found that had a really interesting arguement for sex in heaven.
