Question Detail:

Is there any prohibition in calling your husband by his first name?

Answer :

In the name of Allah, Most Gracious, Most Merciful
Assalaamu `alaykum waRahmatullahi Wabarakatoh
It is compulsory upon the wife to respect her husband. If calling her husband by his name is regarded as disrespectful by him or in that family or community, then it will be prohibited for her to call her husband by his name.
And Allah knows best
