I think there’s a valid conversation to be had about weapon sex in a relationship in the sense of using it to manipulate your partner into doing what you want. But generally speaking if the agreed established expectations of that relationship (whatever they may be) are not being met on either side, you cannot expect the other side to happily engage in sexual expressions of love
I would argue that those consequences are necessary because clearly there are needs that are not being met on both sides of the relationship. If one partner feels that they shouldn’t have to meet certain emotional expectations in order to have sex with their partner and the other one feels like they do then that’s clearly an impass. Either they reestablish the expectations or they break up.
