I usually avoid one one 1 games like the plague, but I decided to give this game a chance and really enjoyed it. I enjoy games that have a lot of character development before any H stuff happens as it adds a ton of context when the H stuff does go down and this game, depending on how you choose to play, did just that. I didn't experience any H stuff until around chapter 4 other than minor grope scene's, then I decided that her character development was enough for me and decided to take her down the forced prostitution route. So really it all depends on you, if you want gratuitous porn you can make her a prostitute or loose to all the boss's / make dumb choices and turn her into a slut in chapter 1, or if that's not your thing you can wait. You can even do a virgin clear I believe.
Not sure if this answers your question but hopefully it offers some insight.
