Knowing how to insert a large anal plug correctly protects against discomfort. Warm up with smaller plugs from the anal plugs collection before moving to this large-size range. Once ready, position yourself comfortably, apply lube liberally, and guide the spherical head in at a controlled angle — the body-safe materials mean no irritation concerns as you ease in. The wide base keeps everything safe and recoverable.
