Husband demands wife perform oral sex on him
One of the sisters is asking, saying that she is a practising young woman who got married six months ago. (She says) her husband demands she suck his penis, and she asks if this is permissible or not?
All praise is due to Allaah (alone). There is no doubt that (the request of) this practise from the husband of the questioner is a disgusting practise and obviously disliked. It also undermines the (good) manners between the husband and wife, and could possibly be a cause for (each partner) disliking (the other) and (leading to) separation (divorce).
‘Aa'ishah (radiyallaahu anhaa) was one of the wives of the Messenger of Allaah (sallallaahu alayhi wa sallam), and it has been narrated on her authority that:
"He (sallallahu alayhi wa sallam) did not see this of her and she did not see this of him." (i.e. they did not see each other’s private parts, even though it is permisible).
As regards the ruling about this, then the least that can be said about it is that it is disliked, and Allaah knows best.

Note: The basic ruling regarding the wife seeking pleasure of her husband’s penis is that of permissibility, however, that which is feared is that this act may lead to possible oral intake of sperm or prostatic fluids. The Hanaabilah have indicated the permissibility of a wife kissing her husband’s penis, as is mentioned in ((al-Insaaf)) of al-Maardeenee [Volume 8, Page 33], and this is the opinion of Ibn ‘Aqeel and other than him. Also, Asbagh from the Maalikiyyah has indicated the permissibility of a man kissing his wife’s vagina as is mentioned in ((Tafseer al-Qurtubee)) [Volume 12, Page 231].
