deformed anus
An anus in a relaxed or gaping state that has been deformed due to medical reasons(such as diseases), sexual development, or physical causes(such as manipulation with fingers or instruments).
Typically, sexual development refers to shape changes caused by repeated or prolonged sexual activity, such as anal masturbation or anal sex.
This deformation results in unusual appearances such as a heart, triangle, vertical line, puffy, or other non-typical forms — rather than the more common appearances like an O, X, or *.
