Is There Sex in Heaven?

Christian philosopher Peter Kreeft answers this question in his book, Everything You Ever Wanted to Know About Heaven. Here is an excerpt and his main conclusion:

"Specifically human reasons for intercourse include (1) consummating a monogamous marriage and (2) the desire to express personal love. As to the first, there is no marriage in Heaven. But what of the second?

I think there will probably be millions of more adequate ways to express love than the clumsy ecstasy of fitting two bodies together like pieces of a jigsaw puzzle. Even the most satisfying earthly intercourse between spouses cannot perfectly express all their love. If the possibility of intercourse in Heaven is not actualized, it is only for the same reason earthly lovers do not eat candy during intercourse: there is something much better to do. The question of intercourse in Heaven is like the child's question whether you can eat candy during intercourse: a funny question only from the adult's point of view. Candy is one of children's greatest pleasures; how can they conceive a pleasure so intense that it renders candy irrelevant? Only if you know both can you compare two things, and all those who have tasted both the delights of physical intercourse with the earthly beloved and the delights of spiritual intercourse with God testify that there is simply no comparison."
