This is a good and authentic hadith.

6 - Chapter: What has been related about the description of the intimate relations of the people of Paradise

2711 - Mahmud ibn Ghaylan and Muhammad ibn Bashshar narrated to us, they said: Abu Dawud al-Tayalisi narrated to us, from 'Imran al-Qattan, from Qatadah, from Anas, from the Prophet, peace and blessings be upon him, who said: "The believer will be given in Paradise the strength of such-and-such for intercourse." It was said: "O Messenger of Allah, will he be able to endure that?" He said: "He will be given the strength of one hundred." (2)

In this chapter, there is also a narration from Zayd ibn Arqam.

This is a sound and authentic hadith, known only from the narration of Qatadah from Anas through the narration of 'Imran al-Qattan.

(1) Authentic due to corroborating evidence, like the preceding one.
(2) Hasan; 'Imran al-Qattan — who is Ibn Dawar — is weak, but his narrations are considered in corroborations and witnesses. Ibn Hibban recorded it in his "Sahih" (7400). See the complete grading of it there. In this chapter, there is also a narration from Zayd ibn Arqam recorded by Ahmad (19269), and it is an authentic hadith. See the rest of its grading there.
