If you feel uncomfortable, get to a place where other people are, scream or yell for help, or get in your car or apartment and lock the door immediately. You need to be thinking coherently and feel in control in order to communicate clearly. Keeping that in mind, here are some tips that might reduce the risk of being accused by another of sexual misconduct. Never assume that you know what a woman wants sexually. Her dress and her behavior are not accurate communicators of what she wants to happen.
Assumptions can lead to jail sentences.
The more intoxicated or affected by drug use EACH of you is, the more likely you are to misjudge or miscommunicate in any situation. Physical and verbal communication are BOTH important. If permission is being given BOTH ways without coercion, you are on safer ground. Lights in all entrances and hallways. Secure locks or double lock on every exterior door.
