Aha, it seems to be an options problem in your case. Well, slut points make some things easier and I can calm you on the tipping point amount. On the diplo route I play, pursuing Mom, Sis, Karla and to an extend Emma, a dozen slut points are no problem as long as you keep up gaining Confidence, Corruption and Love points. In one playthrough I have Mom securely on alpha route with
despite her having 18 slut points. But this is a high amount where you have to be careful watching the other point scores. A dozen- slut points leave you more breathing room for problematic choices with other variable points.
Naturally if you go for the happy voyeur, sharing later, Diplo focused on just one girl or miserable beta routes, then high slut scores are important. If you do Alpha and Diplo focused on Mom and/or Sis routes, then low to moderate slut scores are better.
What I personally look forward to solve is the background action. Marcus and family are clearly not quite the "average" employer/friends, but what shines through more than once: Auntie Liza is not only influential, but seems to be involved in gray and shady business zones. Bringing the MC family to Hawaii seems to be made with further ideas in mind by Liza. Looking forward to see how this is solved in the various paths.
