Lo! We have created them a (new) creation, And
made them virgins, Lovers, friends, For those on the right hand;
Quran 56:35-38
Abu Umama narrated: "The Messenger of God said, 'Everyone that God admits into paradise will be
married to 72 wives; two of them are houris and seventy of his inheritance of the [female] dwellers of hell. All of them will have libidinous sex organs and he will have an
ever-erect penis.' "
Sunan Ibn Majah, Zuhd (Book of Abstinence) 39
It was mentioned by Daraj Ibn Abi Hatim, that Abu al-Haytham 'Adullah Ibn Wahb narrated from Abu Sa'id al-Khudhri, who heard the Prophet Muhammad PBUH saying, 'The smallest reward for the people of Heaven is an abode where there are eighty thousand servants and
seventy-two houri, over which stands a dome decorated with pearls, aquamarine and ruby, as wide as the distance from al-Jabiyyah to San'a.
Al-Tirmidhi, Vol. 4, Ch. 21, No. 2687
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 [i.e. Muslim] will marry
seventy [sic]
houris, besides the women he married on earth, and
all will have appetizing vaginas.
Al-Itqan fi Ulum al-Qur'an, p. 351
Anas said, Allah be well-pleased with him: The Messenger of Allah said, upon him blessings and peace: “
The servant in Paradise shall be married with seventy wives.” Someone said, “Messenger of Allah, can he bear it?” He said: “He will be given strength for a hundred.” From Zayd ibn Arqam, Allah be well-pleased with him, when an incredulous Jew or Christian asked the Prophet, upon him blessings and peace, “Are you claiming that a man will eat and drink in Paradise??” He replied: “Yes, by the One in Whose hand is my soul, and
each of them will be given the strength of a hundred men in his eating, drinking, coitus, and pleasure.”

This
[Qur'an 78:33] means round breasts. They meant by this that the breasts of these girls will be
fully rounded and not sagging, because they will be virgins, equal in age.
Tafsir Ibn Kathir, Abridged, Volume 10 Surat At-Tagabun to the end of the Qur'an, 333-334
“According to Prophet Muhammad (SW), the Hurs of Paradise will be pure women, free of menstruation, urine, stool, cough and children. The Hurs will sing in Paradise on divine purity and praise—we are most beautiful Hurs and we are for the honored husbands. Muhammad said that an inmate of Paradise will have the sexual strength of 70 men. Muhammad said, “An inmate of Paradise will have 500 Hurs, 4,000 unmarried women and 8,000 widowed women. Each of them will keep embracing him for the duration of his whole worldly life.”
