Definition and Pronunciation
Sub (IPA: /sʌb/; pronounced SUB) is an informal abbreviation of submissive used primarily in BDSM and power-exchange relationships. It refers to a person who consensually chooses the submissive or receiving role during BDSM activities or relationship dynamics. A Sub voluntarily agrees to this role within negotiated boundaries, and the relationship is based on informed consent, mutual trust, communication, and respect.
Easy Explanation
A Sub is a person who prefers the submissive role in a consensual BDSM relationship or scene. Depending on the agreement between partners, a Sub may choose to follow the guidance or direction of a dominant partner within clearly established limits.
Being a Sub does not mean giving up personal rights or accepting mistreatment. Healthy BDSM relationships emphasize informed consent, personal autonomy, mutual respect, safe words, and ongoing communication. A submissive role exists only because everyone involved freely agrees to it.
