No you can't, NLT decided to make it a linear game so you need to play (and see) everything, if you want to complete the game.
You can partially diminish the time scenes skipping on the dialogues, but being them mini movies you will still be forced to look until they end, so if you don't like group and lesbian scenes that much you can't do more than what I wrote to "lessen" the pain let's say.
It's up to you, the game is good and worth the play imho ( even though it become a little messy toward the end), but that's all I can say to help you.
