If you aren’t feeling it, stop and don’t feel any guilt. Most people don’t have that much free time in their life between work, school, family, etc and it isn’t worth spending that precious time doing something you don’t enjoy. I love Murakami’s work because I really enjoy the magical realism and surreal elements and I’m fine with powering through all the weird horny parts to get to the fun stuff. Other people struggle with the weird horniness or don’t enjoy his style of dialogue which is completely fine. There are plenty of other great authors out there.
