The Abbasid-era belletrist+theologian al-Jāḥiẓ (d. 869) did not tolerate prudishness. In his *Mufāḫarat al-Jawārī wa’l-Ġilmān*, he pokes fun at a man who displays piety by rearing in horror at the mention of sex by listing the ribald quips of the Prophet's companions ...

It's ignorance that causes such attitudes, he said. "If only he knew," Jāḥiẓ writes, while at Mecca's Sacred Mosque, the Prophet's very uncle Ibn ʿAbbās recited a lewd line of poetry while dressed in pilgrims' garb (muḥrim):
The women walk beside us with the softest sound//

it augurs well that her tender body we shall pound!"
“Why that’s obscene!” someone said, but he replied, “It’s only obscene if said in women's company!”
[This is a bit of a semantic point: the word for “obscenity (rafaṯ|رفث)” actually refers to obscene words directed to women.]

The Prophet's cousin and brother-in-law, ʿAlī ibn Abī Ṭālib, comes next in Jāḥiẓ's list. One day ʿAlī came unexpectedly to visit a man in Baṣrah, so he called out, “Who’s in these living quarters?”

The man said, “The finest ladies of all the Arabs!” And ʿAlī replied, “The man who lengthens his father’s dick uses it to gird his loins!”
[That is, a man boasts about his father to make himself look better.]

Also on his list is Abū Bakr al-Ṣiddīq, who quite famously told one of the unbelievers at the signing of the treaty of Ḥudaybiyah to “Go suck on [the goddess] Allāt’s clitoris (umṣuṣ baẓr allāt)!”

This line appears in the famous ḥadīth in al-Bukhārī's collection ( https://sunnah.com/bukhari/54/19 ), but here in this edition of Jāḥiẓ's text Abū Bakr allegedly said something slightly different: i.e., “You're clinging to Allāt’s clitoris by your teeth (ʿaḍaḍta bi-baẓr allāh)!”

Another uncle of the Prophet to make his list, Ḥamzah ibn ʿAbd al-Muṭṭalib, cried out while slaying the infidel Qurashī Ibn Sibāʿ at Uḥud, “You son of female clit-cutter!” (lit. you son of a woman who cuts off clitorides, a female circumciser of women).

Jāḥiẓ adds a nice comment on the end of the list, noting that these words exist to be used and were it not so, they wouldn’t have any meaning in the first place and they would be absent from language altogether.
