New Delhi: A Calcuttan now based in Mumbai has moved the Supreme Court seeking a ban on pornographic websites available in the country, saying her husband's addiction to watching porn had ruined her married life.

In an affidavit filed on Thursday, the woman, a project manager with a non-government organisation, said her husband had even lost his virility because of his addiction and was pressing her for divorce through mutual consent.

"It appears to me that my husband is scared to initiate natural sexual intercourse with me, which is ruining my married life," she said.

"I am a victim of pornography. I most respectfully want to bring to the notice of the Hon'ble Court the havoc being caused on the Internet by porn videos...," the woman said, adding that her "husband refuses to reform himself from the addiction of watching pornography".

The couple had got married in March 2016 in Mumbai. While the woman, who was born in Calcutta, shifted to Maharashtra for her job, her husband is also involved with an NGO that he runs in Mumbai.

The woman, who said she came from a middle-class Bengali family and was brought up with a "good education, etiquette and high moral values", alleged that her husband spent a lot of his time watching porn, "easily accessible through the Internet", which had made his mind "perverted and ruined my matrimonial life".

"... ever since my marriage my husband has not provided me with marital bliss. It seemed from my husband's actions after marriage that he is suffering from lack of virility and vitality and thus is unable to initiate sexual intercourse. However, my husband has at times forced me to have unnatural oral sex with him against my wishes," she said.

"Thus, my husband is exhibiting abnormal behaviour ruining my married life," she said in the affidavit filed in the context of a 2013 public interest plea (PIL) by a Madhya Pradesh-based petitioner, Kamlesh Vaswani.

Vaswani, who had filed his PIL through advocate Vijay Panjwani, had sought a ban on pornographic content easily available on websites.

The apex court had earlier directed the central government to come up with a mechanism to combat the menace posed by these sites, which the petitioner had cited as a major reason behind gang rapes, including the December 2012 sexual assault and murder of a young paramedic.

In her affidavit, the woman said her husband has been addicted to porn since the 1990s, when he was a teenager, but she learnt of his obsession only after their marriage.

"I have found in my matrimonial home, old porn videos and CDs which my husband collected over the years and this exposes his fascination for hardcore porn and reflects his perverted lifestyle," she said.

"My husband used to watch porn through his VCR and computer... as a result (he) failed in his tenth class board examination in the year 1997 because of his addiction to porn, which distracted him away from his studies and ruined his personality," she said.

Now, the woman said, her husband's obsession was interfering with his daily life. "Because of this addiction of watching porn... he is ignoring his day-to-day activities and my marriage is getting ruined as my husband is indifferent to my physical and other material needs," she said.

The apex court has not fixed any date for taking up the affidavit.
