Can I have liability for having sexual relations with some one?

I am a lawyer in CT and practice in this area of the law.  The rule of thumb is never to have sex with a girl that you know is drunk or have reason to believe is drunk and you are not in a relationship with her as the inference from the state's perspective is that you took advantage of her.  In this case, it sounds like she knew what she was doing as she was aware where the condom and the lube was and there are likely no signed of forced penetration (i.e. rape).  Therefore, i do not think that you have real exposure here, however, i strongly suggest that you obtain a lawyer if in fact charges of any kind are pressed.  I also suggest that you do not speak to the police without a laywer present.
