If you want you can reject every single sex scene in the game, except for the ones with her boyfriend Andrew. She will still suffer a certain amount of harassment in the Bar for instance during Chapter 1, but even there you can avoid all the sex stuff. So yeah, you can pick and choose which sexy content you want to include. And since the start of Chapter 2, there are now naughty alternatives, to most of the more extreme blackmail content (like the Jeremy route, in the hospital, or in the Bar). So now if you don't want Anna to follow routes where she gets abused or humiliated, you get alternative sex scenes where that doesn't happen
