Hinduism(and also Buddhism) doesn’t really have a heaven or afterlife AFAIK. There is a concept of karma and rebirth, where if you perform good deeds you’re reborn into better circumstances, and the eventual goal is to attain enlightenment so that you can be free of the cycle of rebirth and become one with the universe. Or some such. I don’t think what comes after enlightenment is depicted.
Nor (I think) is it strictly necessary to be a Hindu to be a part of this cycle. You can achieve one-ness with the universe in a number of different ways, only one of which is prayer to god. It’s all very scattered.
It would be hard to take any inference from the Qur’an passages themselves other than that the Houris are there for sexual pleasuring by and with dead believers. If you start throwing in descriptions from the hadith, the specific sexual fantasies get quite a bit more graphic–and bizarre. For example, one guy thinks they will be 90 feet tall, so one has to wonder if that would even be pleasurable (mechanically speaking). Another guy is pretty sure they don’t have any hair on the perineum; others state they don’t menstruate, defecate, urinate or get pregnant.
I think the thrust is that Houris start out being virgins, and given the culture that created them, I would say the attraction of this is that no other man has gotten any where near the naughty bits, which are sort of preserved unsullied through eternity for the sole purpose of pleasuring that one dead believer.
Along with the Houris, you get a bunch of other servants plus a bevy of eternally young boys.
Since we cannot say scientifically that Houris are false, I think you can pretty much attach your own fantasies regarding other characteristics at will…
