An Australian senator this week quoted out author Dan Savage to claim that most gay men find having one partner to be “unrealistic and unnatural.”

In a 13-minute speech on the Senate floor, Family First Senator Bob Day argued against passage of a bill that seeks to alter the nation's marriage laws to end the exclusion of gay and lesbian couples.

“In places where gay people, typically men, have been able to form recognized unions, they do not necessarily equate their commitment to monogamy,” Day told colleagues.

“The term 'monogamish' … has now been coined, a sort of 'open marriage' … as they feel a restriction to one partner is unrealistic and unnatural,” Day said. “This 'monogamish' compromise is nothing short of surrender. As usual, all the guarantees about marriage staying the same have come to naught.”

The term “monogamish” was coined by Savage, who is 51, and has been writing a sex advice column for Seattle's The Stranger since 1991.

In Savage Love, Savage often talks openly about his “monogamish” marriage to Terry Miller.

To be sure, Savage says monogamy works for most couples and often talks about its perks, including paternity, less risk of disease and less risk of emotional attachment.

“It's one thing to mess around and have a low stakes sexual encounter with someone else,” Savage said in 2013. “But to go on a date with someone else, to develop feelings for that person, that gets tough. And that's a risk.”

Day also argued that allowing two men or two women to marry would lead to marriages involving three people.

“If this bill seeks marriage equality, what is it trying to protect equally? What relationships then are not marriages? Why would redefining marriage stop at same-sex relationships? The bill talks about two people, but why not three?” he rhetorically asked.
