No, though it depends on how you see it, some high scores push you some times in a road, you could consider it locks you out of not having them. ^^one fast question ......it is possible that manyy points keep you out of some scenes....? i know there are scenes that you need certains mileage but ....too many points of some kink or traits lock you out?
You should try them, they are pretty sweet (just have to chose another sexuality for Katherine at the pool during chapter 3).I can't remember if I did or not to be honest.
