The houris are mentioned in several passages of the Quran, always in plural form. No specifics are even given, though, as to the number of houris that should be available to each believer.
As for the gender of the houris: the Quran doesn't indicate that only men would be granted the company of houris—in fact, it can be inferred from the context that both men and women believers will have a plural number of houris for themselves.
In the same collection of hadiths, however, the following is judged strong (hasan sahih):
That the Messenger of Allah said: "There are six things with Allah for the martyr. He is forgiven with the first flow of blood (he suffers), he is shown his place in Paradise, he is protected from punishment in the grave, secured from the greatest terror, the crown of dignity is placed upon his head—and its gems are better than the world and what is in it—he is married to seventy two wives among Al-Huril-'Ayn of Paradise, and he may intercede for seventy of his close relatives."
Ibn Kathir says that the houris "are delightful virgins of comparable age who never had sexual intercourse with anyone, whether from mankind or Jinns, before their husbands." by commenting, "in the other life, after they became old in this life, they were brought back while virgin, youthful, being delightfully passionate with their husbands, beautiful, kind and cheerful."
Ibn Kathir also stated that Muhammad confirmed that there would be sexual intercourse in Paradise
The sensual pleasures are graphically elaborated by Al-Suyuti (died 1505 ), Koranic commentator and polymath. He wrote: "Each time we sleep with a houri we find her virgin. Besides, the penis of the Elected never softens. The erection is eternal; the sensation that you feel each time you make love is utterly delicious and out of this world and were you to experience it in this world you would faint. Each chosen one [ie Muslim] will marry seventy [sic] houris, besides the women he married on earth, and all will have appetising vaginas."Virgins? What virgins? | Books | The Guardian
