IT HAS BEEN A LONG TIME SINCE I'VE READ THIS WORK. MOST LIKELY IT IS FROM, RECOLLECTION, ONE BASED ON HETEROSEXTUAL RELATIONSHIPS. ABSTINENCE UNTIL THERE IS A MUTUAL AND SPIRITUAL AGREEMENT INVOLVED. BUT THAT IN HEAVEN THE ANGELS NEITHER MARRY NOR ARE GIVEN IN MARRIAGE AND THERE IS NO SEXUALITY INVOLVED BUT ANDROGYONOUS BEINGS . I WOULD HAVE TO READ IT AGAIN BUT KNOWING THE AUTHOR FOR MANY YEARS I CAN RECALL THIS GENERAL IDEA.
