Gangbang
Gangbang refers to a form of group sex in which a significantly larger number of active or penetrating participants engage sexually with one or a few passive participants. The term comes from English and is now usually used for consensual group-sex scenarios. Historically, it could also carry a violent connotation, but this must be clearly distinguished from consensual practice.
Clear agreements, explicit consent from everyone involved, and respectful attention to boundaries are essential in such situations. Because the number of contacts is higher, the risk of sexually transmitted infections increases; protection, hygiene, communication, and the ability to stop at any time are therefore especially important. Non-consensual or coerced acts are clearly unacceptable.
