NAIROBI, Kenya (CNN) -- A Kenyan man has sued activists who called on women to boycott sex to protest the growing divide in the nation's coalition government.

James Kimondo said the seven-day sex ban, which ended this week, resulted in stress, mental anguish, backaches and lack of sleep, his lawyer told the state-run Kenya Broadcasting Corp.

The lawsuit filed Friday claims lack of conjugal rights affected Kimondo's marriage and seeks undisclosed damages from the G-10, an umbrella group for women's activists, KBC said.

The women's caucus caused a national debate when it urged women to withhold sex to protest increasingly frosty relations between President Mwai Kibaki and Prime Minister Raila Odinga.

Citizens of the east African nation are frustrated by a shaky coalition government, which was formed after post-election violence killed more than 1,000 people in 2008. The wrangling between Kibaki and Odinga has sparked fears of more violence.

Gender activists say they are not worried about the lawsuit.

"I have not been served with the papers, but I was told they are coming and I am eagerly waiting," said Ann Njogu, executive, director of Centers for Rights Education and Awareness. "It will be interesting to see the face of a man who is not willing to abstain for the sake of his country."

Despite the lawsuit, Njogu said, the boycott was successful.

"The principal leaders met as a result of the boycott, and I understand that they are setting up reforms to look into the country's internal security," she said.

Plans are under way for women activists to meet with Kibaki and Odinga, according to Njogu.
