Why does a person expose themselves to others?

If a person were to expose themselves emotionally to someone, it may be because the person feels unstable and feelings like they need someone there to talk to and care for them if their going through a tough or troubled time.

If a person were to expose themselves physically in a naked state, the person may feel a sexual connection with their audience and is trying to hint to them. They may have a mental issue and don't realize what they are doing. They may feel good about their body and feel no issue about appearing naked in front of other human beings and lastly they may be under the influence of drugs. In a few cases, some do it to get locked away. An example was a mentally ill person who was constantly bullied, so he disrobed and called the police to get him, figuring that with his history, he would be hospitalized.
