I entered into my marriage assuming my partner was negotiating in good faith. If she says something bugs her, it bugs her. Collectively we can either spring for Cognitive-Behavioral Therapy for her, or I can pick up my pants after I shower.

If your partner needs to have their way in all things, then there may be a deeper trust issue to resolve and/or they might not be ready for a committed relationship.

Edit: rereading above I can see it coming off as a little flippant. At the core I believe we all have things we do and feel that are not rational. I don’t think you can reason your way out of them. You can’t rationally argue away a feeling. You can do therapy to try to change it, or you can remove the negative stimulus.
