BANGKOK: Just months after telling its members to serve their husbands better than prostitutes, prompting widespread criticism, the Obedient Wives Club of Malaysia has stirred further controversy by publishing a guide to Islamic sex.

The 115-page pocket-sized book, which will outrage many Muslims and non-Muslims, says a Muslim man can have sex with all of his wives at the same time.

Under strict Islamic tradition a man can have up to four wives if he can provide for them all.

The club prompted an outcry from women's groups and Islamic religious authorities when it was established in June, claiming to have 1000 members.

Malaysia's Minister for Women, Family and Community Development, Shahrizat Abdul Jalil, asked government officials to monitor the club to ensure it would not ''muddle'' the minds of Malaysia's younger generation. But Ms Shahrizat said the government could not restrict the club's activities, saying ''we are after all a democratic country''.
