bedroom

i want to know is it ok and permissiable in islam to have a picture of verses of quran written on it to be hangd in the bedroom where sex is performed by husbend and wife

As-Salamu `Alaykum. Could you please enlighten me about the Islamic ruling concerning divulging one’s bedroom secrets in public? Some people find no shame in discussing such secrets in public. Is such a thing permissible in Islam? Please cite an evidence in support of your view. Jazakum Allahu Khayran.
