<human>: Can you summarize the given text in a few sentences?

I was hanging out with two friends yesterday when one of them revealed to us that she had been raped the past weekend.  She was visiting a friend at a college and ended up going to a guy's room to sleep there (literally), and he forced her to have sex with him twice.  She said it was scary and a bad experience, but talked about it in an incredibly casual way.  She didn't use the word "rape" until my other friend hesitantly brought it up, and she claims she isn't traumatized.  She genuinely did not seem upset!

This is actually similar to another situation that occurred about a year ago when she mentioned that her parents used to beat her when she was in high school as though that was perfectly normal.  No sign of trauma, no sign that she understood the seriousness of the situation. (I let it go at the time because she said her parents stopped when she went to college.  If she'd had younger siblings, I would've pursued it.)

I really don't know what to do.  On the one hand, what happened was absolutely not okay, but if she is really taking it so "well" I'm worried that emphasizing the sexual assault will actually do more damage.  She should probably get tested for STDs though (even though she thinks she's clean because he seemed worried that she might have an STD).
<bot>: Should I broach the subject of my friend's sexual assault if she doesn't seem like she understands what has happened?
