Sex bans have helped form governments in the past.
The partners of Belgian politicians are being urged to go on a sex strike until a government is formed. The country had general elections last June but parties have so far been unable to form a governing coalition.
Socialist senator Marleen Temmerman said after a week of a similar sex ban in Kenya in 2009, a government was formed. Previous attempts to pressure Belgian negotiators into agreement have included a “grow a beard” campaign.
