ERP stands for Erotic Roleplay, which is any role-playing activity performed mostly, or exclusively for the purpose of sexual behavior. It is a type of roleplay that encompasses sexually explicit behavior, often leading up to and including sexually explicit behavior. ERP is particularly prevalent in online MMORPG games like World of Warcraft. Consent is important for many kinds of roleplay, not just ERP. It’s the often unspoken, unwritten rule that keeps players happy and forms the foundation of trust that is necessary for player-driven stories and events. When it comes to roleplaying, explicit consent is important for online ERP for the same reasons it’s important offline: it’s healthier and safer for everyone involved.
