Two couples are suing to have the rest of Kentucky's gay marriage ban struck down after it was partially overturned by a federal judge last week.
The suit asks the same federal judge who ruled that Kentucky must recognize same-sex marriages performed in other states to expand his ruling to allow marriages to take place inside the state.
Timothy Love and Lawrence Ysunza and Maurice Blanchard and Dominque James contend in their suit that not being allowed to marry in their state 'deprives them of numerous legal protections that are available to opposite-sex couples.
Love and Ysunza have been together for 33 years while Blanchard and James have been together for a decade.
James tells the Associated Press: 'We just want to be treated equal to our heterosexual brothers and sisters. If we can get that, we will be satisfied.'
U.S. District Judge John G. Heyburn wrote last week that the state's laws treat gay and lesbians differently in a 'way that demeans them.'
The issue of whether the state should be required to allow same-sex marriages to be performed was not a part of the original lawsuit filed by four other couples who were married outside the state.
The Kentucky ban was one of several passed in US states during the 2004 presidential election that brought Republican George W. Bush a second term.
