Perhaps they would, but by the very theory you lay out, any gene causing such would inevitably fail to take hold. It's not as though there's a separate 'loser' dynasty that evolves gaynesss to cope with its inability to reproduce - if it's unable to reproduce, it dies out.

No they wouldn't. I am sure it is all some game theory puzzle. The societies that had less internal strife due to lessened sexual tension would outcompete those that did not.

This could be passed by the lesbians, who still had to procreate with their male. Which would be likely in this scenario because polygyny is heavily tilted in reproductive favor of the female.

Also the dominant males could easily be queer as hell and still desire to reproduce with their stable of females.

For all we know we come from a species that was primarily homosexual, yet would still copulate for reproduction, and are evolving into heteros.

More likely we come from a species that would stick it in anything because their hormones raged so hard. (that sentence is so gay it proves it!)
