I'm talking about personal values and ethics. I would never advise anyone to sexually assault someone. It's immoral and illegal. Any harm and pain could not be undone. They should try their best to avoid such a situation from happening. If your girlfriend is sexually assaulted, you should feel very painful and angry and should take action to protect her and yourself. This may include seeking professional help, calling the police, or seeking legal support with your girlfriend. It is important that you support her emotionally and do everything possible to protect her from further harm.
