Let's return to the Koran, Islam's font of religious authority. Even if we leave out the racy detail and make allowances for metaphor, we're obliged to admit that Islamic heaven is a pretty rockin' place, with an emphasis on sensual pleasures. The provision of virgins in indeterminate quantities is alluded to at numerous points, and you know they're not just there to fluff the pillows. (In fairness to the Prophet, the physical quality usually attributed to the houris, as they're called, is "wide lovely eyes.")
The food, service, ambience., etc, are great. You're allowed to enjoy things the Koran explicitly denies you on earth, such as alcohol, and you won't even get sick. ("Wine . . . delicious to those who drink it . . . will neither dull their senses nor they will become drunk.") Granted, the whole thing is skewed toward the male idea of a good time, a defect by no means confined to Islam. Were Muhammad to found a religion today, I'm confident that each female arrival in heaven would be assigned a comely stud who would provide fabulous sex and in addition hang the curtain rods the first time he was asked. Granted, also, the emphasis on virgins is a little weird. (Think back on the first nights you've been party to. Was this your idea of great sex?)
Still, you have to admit, heaven as Party Central sure beats the Christian idea of angels with harps.
