@Precipice the comment by @cupcaske123 about sweeping statements wasn't about the prevalence of women engaging in duty sex. It was about women being victims "I don't appreciate such broad sweeping statements victimising all women." No one said all women are victims.
There are things that all women do of course- breathing is one example if you really want to be pedantic.
But to address what I think is the general thrust of your comment -
I believe that a large majority of women do engage in duty sex. I don't have data to support that beyond my own experience, reading and conversations with other women.
I find it is "normal and expected", and not just endured by a few women who ought to know better which seems to be the thrust of your and @cupcaske123 's points, which ironically do actually victimise women.
I think it's complicated and that's why I just posted the article with a couple of excerpts and no personal opinion as the OP.
What I'm more interested in Is hearing whether women think duty sex is any different or worse than doing the dishes - not awful, not the best fun either, but needs done to maintain a functioning household. Or is duty sex unacceptable/ heinous/ rape?
I honestly don't know. But I do wish MN feminism threads wouldn't always degenerate into a fight about whether women as a whole class or individual female posters are good or evil/ virtuous or to blame/ right or wrong. There are more interesting issues at play than petty finger pointing!
