A common physical sign of autoerotic deaths can include:

The presence of evidence of sexual aids is a common physical sign of autoerotic deaths. In cases of autoerotic asphyxiation or other forms of autoerotic behavior, individuals might use various devices or aids to enhance sexual pleasure. This evidence can include items such as ropes, bondage equipment, or other paraphernalia typically associated with solo sexual practices. The context of these aids is crucial, as they help investigators determine the nature of the circumstances surrounding a death that may initially appear to be accidental or otherwise unclear.

Other signs, while they may sometimes occur, are not as specifically indicative of autoerotic deaths. For example, excessive bruising or cuts could arise from various situations beyond autoerotic practices, such as physical altercations or accidents. Therefore, while they can be observed, they are not distinctly linked to the behavior in question.
