>>47703599Anon, the "did" in your second sentence already denotes the past tense. "Did she really rape someone?" would be correct, there is no reason to use "raped" here.
Your third sentence is a bit more baffling. Considering how you got the sentence structure right in your second sentence, it seems weird how it's all over the place in the third one. "Or did it just get too physical" would be correct. Do note how "did" again denotes the past tense, while "get" is in its infinitive form.
I hope you continue to improve your english skills!
