I hope that changes....Yes, In some way. Once the dating system comes (which it will at some point) MC will have to date girls before he'll actually get the sex scenes. In Roxxy's case for example you'll have to beat Dexter and then you can start dating, in Eve's case you'll have to finish her story, etc.
So you'll end their story and then you'll have to date them to unlock more scenes, etc. You'll gain points from dating and you'll only be able to date one girl at a time or points will be subtracted from others. Once you've got enough points you'll be able to take her to prom to get a final scene. At least that's what's know until now, so it may change at some point.
But all of this still quite far away, so if that's what you are looking for, you probably won't have to come to back until mid to late 2021.
I'd rather not have to settle down with 1 when i can live the harem life.
