Um, I'm afraid not. There was only two rape scenes, one with Minami in a train, the other when Kaori falls asleep on a bench. I think holding shift skips the dialogue, so if you are going to do so, let me just say that in the Minami scenes is about you trying to show Minami some consequences for being so nosy, then you come in and use the stun gun you stole from Asuka and you get stabbed, pretend to be a hero (a few One Punch Man references) and do not want to go to the hospital in case they ask for your real name, then continue with your normally. With Kaori, you could just ignore and let her get molested, you could attack and nothing really happens or think a bit before attacking and she does get molested, but you knock the molester out. Oh, and lastly, Faris is a dick and tries to drug girls, but no sex scenes if I remember correctly. In conclusion, no, they are unavoidable, but I gave you all the info to do whatever you wish (I think so at least).
