HEAR ME OUT. PLEASE lol.

It isn't gay if there's no romantic and intimate love between two men. Most of you are already doing it with room mates

Two straight men, marrying each other under the rules of "You can sleep with how many women you want, date whoever you want, romance whoever you want" is probably the greatest way of cheating the system.

You wouldn't have to pay for any "relation upkeep costs"

Two males bringing in income to one house would vastly benefit the both of you

Rent is shared

You even have a greater chance of getting full custody of your children due to the fact that the court would see your home as having "Two Parents".

No false accusation schemes

No emotional drama

And really, There wouldn't be any "Divorce Settlements". There's men who refuse divorce settlements from their wife who's making way more than them out of pride and dignity. Heck, there would probably never be a divorce to begin with.
