But that's the point for the math:

We can say:

x marks the value of this low value woman here, which remains standard.

x+1 would merit this woman's new value if she agreed to dabble in lesbianism and introduces the possibility to a male partner of "if you date me, I might agree to bring another girl into the bedroom and you'll get threesomes."

y marks the value of the man in this instance- a value that has no change from this new piece of data and thus is static.

The conclusions:

If y > x+1, then the woman is with a higher value man than her, and thus she's got her trophy. She would not care to do this and risk losing what she had.

If y < x, then the man is inherently a cuck who would be so beaten down by society he' would not care if she said this because he's chosen to be broken down by her. He would not care if she did this because he's so broken he'd just accept it.

The only way this changes anything is If y > x by 1 or less, in which case the lower value woman, now queer, would now be of equal value to her dude...and thus, both sides would be pissed. Both people in the relationship would know they could do better- both the man (he could either get another woman at a lower value than him who'd kiss the ground that he walked on instead of this person who resents him) and the woman (who has now added enough to her value she could presumably convince a higher value man to settle for her.)
