My friend got raped, what whould i do?!?!?!?

I'm not sure what you can do, but you are right - rape is a big deal. You said she did consent to the sex at first... and well, if she was with a young guy, i'm sure he didn't even pay attention to the "no" she gave him later. He may have been so involved in the act itself he wasn't aware of what she was saying? Not a good excuse, but it is possible.

She doesn't remember who raped her? That's odd, was she drunk? High?

If your friend reports the rape, the police will have very little to go on - no idea who did it? No rape kit done at the hospital.

After thinking about it, the best thing you can do is ask your friend if she's talked to someone about it if it's impacted her emotionally. Let her know you don't think it's a good idea to walk around struggling with something, when there is help. You could recommend talking with the school counselor.

Take care.

Is it a big deal when the Dr sticks his finger up your bum hole?

Rape is no big deal UNLESS YOU MAKE IT ONE, how you judge it will determine how you feel.

I highly respect her for being tough and a non drama queen, I have 0 respect for you. (doing something will probably make it worse for her, which would be typical for your type)

Respect her wishes. Although you are her friend and you want to protect her, she doesn't awe it as a big deal. One day she may, then you report it. :)

Let her run her own life. If she is satisfied there is no need for your concern.
