Seducing My Ex Boyfriends’ Uncle

And then u see people start crying (if men can have a harem so can women!)
Alright, give me 1 viable logical reason to why that would ever be beneficial.
A man having multiple wives means more offsprings, and each and every one of them would know who the father is, while the man CAN take responsibility for all of them if they decided to have multiple wives to begin with.
A woman with multiple husbands? U not only denied other women the blessing of having kids and falling in love but u even denied your own son or daughter their right of knowing who their real father is, and denied the father of knowing who their own kid is.
This is so insanely stupid it f*ck*ng hurts.
Pleasure isn't the f*ck*ng point.
