My father was a minister and believed in the resurrection of the body. That is, in the afterlife, we maintain some corporeal form with all our sense intact. He also said that God does not take away the gifts that he has given up and that our sexuality is one of those gifts. The logical consequence of this is that sex can continue in heaven, although we may prefer some new gift instead. Given that conclusion, plus the fact that, biblically speaking, marriage ends with the end of our earthly life ('til death do us part), in heaven we can finally enjoy sex as it's meant to be: an expression of intimacy among people who are or would like to be connected and a gift we give to others. Contrast this with the here and now where that kind of sex almost always engenders jealousy and anger.

For those of you that think I'm bound to hell for this kind of thinking, my father also believed that hell is the absence of God, not a place where red demons with forked tails are constantly prodding condemned souls into pits of everlasting fire. So it will be my choice, to accept or reject God. God loves all his children and forgives them. The question is whether or not we can forgive ourselves.
