is unnatural sex haram in islam? My husband insisted me to insert cucumber into my vagina but i opposed due to that he got angry and not talking to me. What to do ? Please tell me.

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and messenger.

A man should live with his wife in kindness and in a manner that involves a noble character and good customs. Allaah says (what means): {...And live with them in kindness...} [Quran 4:19] In his interpretation of this verse, Al-Aloosi said in his Tafseer, Rooh Al-Ma’aani: " {And live with them}, means having good conduct with them, and {in kindness.} refers to what is not known to be reprehensible in the Sharee'ah or by common virtue. What is meant here is to be just with them in terms of spending the night with them, providing for them, and treating them in a good manner in deed and word.” [End of quote]

This treatment of your husband is not kind at all but rather an evil act that indicates his harsh nature and the unsoundness of his Fitrah (disposition/nature). Therefore, you have the right to refuse your husband's request if he asks you to do that and you have the right not to obey him in this. Indeed, it is strange that he gets angry when you refuse and he does not talk to you because of your refusal. There are certain conditions for ceasing to engage in relations with one's wife as clarified in the noble Sharee'ah and as we have mentioned in Fatwa 85402and  84120.

Finally, we advise you to be patient with him and advise him in a good and gentle manner and also to supplicate Allaah to correct him and help him to regain his reasoning.

Allaah Knows best.
