All perfect praise be to Allah
So, after a few days of this question and without a proper answer, i decided to gather some references which i could from internet and compile them here.
As i have said earlier in comments that i have read on many places that sex between human and jinn is possible. Even i had read some reports of jinn and human marriage. But in this question i will try to stick with sex between human and jinn. Below are things i found.
Yes this hadith is authentic but has different explanation by scholars. The point is all those explanations are not contradictory, so we will accept all non-contradictory explanations of all forms.
From the above source you mentioned, they quote:
Shaykh al-Islam and true Imam, al-Jalal al-Suyuti (Allah have mercy on him) said in his book on jinns, “Ahkaam al-Jaann” (ed. Khalid `Abd al-Fattah Shibl, Cairo: Maktabat al-Turath al-Islami, 1989, p. 24-25):
The truth is that it is possible for human beings and jinns to have
intercourse and al-Tha'alibi mentioned [in his Tafsir] that that is
the meaning of {and be [O Iblis] a partner in their [human beings’]
wealth and children} (17:64). Al-Hakim al-Tirmidhi [in Nawadir
al-Usul, Asl 76 and Asl 207] and Ibn Jarir [al-Tabari in his Tafsir
(22:248)] narrated that Mujahid said: “When a man has intercourse with
his wife and does not name [Allah], the jinn coils around his urethra
and has intercourse along with him. That is the meaning of the saying
of the Most High: {whom neither man nor jinn has touched before them}
(55:56) [cf. also al-Baghawi in his tafsir under that verse].” … Ibn
`Abbas said: “The epicenes (mukhannathoon) are the sons of jinns.
Allah and His Messenger forbade that a man have intercourse with his
wife during her menses; when he does, Shaytan is there before him and
then she may get pregnant and will give birth to a mukhannath.”
You can read other explanations/tafseer of these ayahs and hadees here. And they seem to tend to the other meanings than this one.
Read this odd information too, there were no apparent evidences so i didn't quoted.
And Ibn Jebreen on sexual intercourse between a human being and a jinn [fire spirit], this also lacks any proper evidences, but it is a proper fatwa from renowned scholar.
From this fatwa, as expected on this kind of issue, we find difference of opinion on this issue in scholars. Some even deny this possibility. But many(especially those with experience in spiritual healing etc) do believe in this as mentioned above.
Also this is a separate topic of human and jinn marrying each other,
So, we can say that there is nothing definitive about this matter from quran or hadees, this is all by people's experiences and relating it with their understanding of quran and hadees. But, it's a fact that most of the people attached with this world of jinns etc do believe in this.
Allah knows best.
