Just putting my two cents in here, but I have to agree with the dev,
@darkhound1 that exploring and finding the solutions is half the fun. I also commend him for having the patience of Job to continue to answer the same questions over and over again.
I get it, we live in an instant gratification world, but serious read a few pages of posts and most answers can be found there. All the console commands are there if you want to 'cheat' and avoid a lot of the grind. Whether a scene is wadrobe dependent and the girl needs to be wearing a specific outfit like Aly's pec training. What your lust level needs to be. For example to get a bj from Desire during the housekeeping scene it needs to be at 75.
Click on the phone app and search through the girls and available appoinment and scenes. If a picture isn't showing, you haven't completed the said appointment or scene. You can also click on the blank placeholder and it will tell you what the scene is supposed to be. Like play poker with Alice. Win at poker with Alice.
Lastly, find the posts with directions for using 'UnRen.bat' which will unlock a folder named 'Images'. All the CG's are there with sub folders for appoinment, characters and events among others. Within them you can see the renders and figure out what scene the artwork is for if the name of the pic doesn't tell you.
Not condemming anyone, but as my grandfather used to say, "If all else fails, read the directions."
